Which temperature scale has a smaller degree?

Fahrenheit has the smallest one degree change between degrees.

Which temp scales have equal sized degrees?

The Kelvin scale is related to the Celsius scale. The difference between the freezing and boiling points of water is 100 degrees in each, so that the kelvin has the same magnitude as the degree Celsius.

Which of these units of temperature is larger a Celsius degree a Kelvin Both are the same size none of the above?

Which is the largest unit: one Celsius degree, one Kelvin degree, or one Fahrenheit degree? The Celsius degree and the Kelvin degree are the same size. The scales only differ by an offset, not by the size of the degree unit. For Fahrenheit, there are 180 degrees between boiling and freezing (212°F-32°F).

What kind of molecular motion that mostly relates to the temperature of a substance is?

Temperature is related to the random motions of the molecules in a substance. In the simplest case of an ideal gas, temperature is proportional to the average kinetic energy of molecular translational motion.

How does the size of a degree differ among the temperature scales?

Because the difference between the freezing point of water and the boiling point of water is 100° on both the Celsius and Kelvin scales, the size of a degree Celsius (°C) and a kelvin (K) are precisely the same.

Which of the following temperature scales does not have negative temperatures?

At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale.

At what temperature do the combined effects of contraction and expansion produce the smallest volume of liquid water?

At what temperature do the combined effects of contraction and expansion produce the smallest volume for water? 4 degrees. Why does ice form at the surface of a body of water instead of at the bottom?

What is temperature at molecular level?

At the molecular level, temperature is related to the random motions of the particles (atoms and molecules) in matter. Because there are different types of motion, the particles’ kinetic energy (energy of motion) can take different forms, and each form contributes to the total kinetic energy of the particles.

Which of these units of temperature is larger?

The Celsius degree is larger because there are 100 Celsius degrees between the freezing and boiling points of water, but there are 180 Fahrenheit degrees between the same points.

What role does temperature have in the direction of heat flow quizlet?

What role does temperature have in the direction of heat flow? Heat flows spontaneously from high temperature to low temperature. How is the energy value of foods determined? The food is burned and the energy released is measured.

Which of the following expands most when the temperature is increased?

Helium
Which of the following expands most when temperature is increased? Reasoning: Helium expands more because it is a gas.

How does this compare with the heat needed to raise the temperature of the same mass of water through the same temperature difference?

How does this compare with the heat needed to raise the temperature of the same mass of water through the same temperature difference? This value is less than the heat needed to raise the temperature of the same mass of water through the same temperature difference.

Which warms faster when heat is applied?

Iron warms up faster when heat is applied.

What are the temperature scales of freezing water on the Celsius and Fahrenheit scales for boiling water?

Temperature is a measure of the average kinetic energy of the particles in matter. The Fahrenheit scale defines the freezing point of water as 32°F and the boiling point as 212°F. The Celsius scale sets the freezing point and boiling point of water at 0°C and 100°C respectively.

What role does temperature have in direction of heat flow?

Heat energy is the energy which transfers from hot object to cold object. So the direction of heat flow only depends on the temperature change. Therefore, the temperature determines the direction of heat flow.

Which warms faster when heat is applied iron or silver which has the lower specific heat capacity quizlet?

Silver warms up faster than iron. Iron warms up faster than water. Does a substance that heats up quickly have a high or a low specific heat capacity?

Does a thermometer measure its own temperature quizlet?

Only translational kinetic energy affects temperature. 6. What is meant by the statement that a thermometer measures its own temperature? The thermometer measures the temperature at the point of measurement only, not the temperature of the neighborhood.

Which is commonly known as absolute zero?

absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale.

When can thermal energy in a system move from lower to higher temperatures?

According to the (second) law of thermodynamics, the thermal energy of a system changes when work is done on the system. The thermal energy of a material (increases) when the temperature of the material increases. (Refrigerators) transfer thermal energy from a cooler area to a warmer area.

What are the temperatures of freezing water in the Celsius Fahrenheit and Kelvin scales?

The freezing point of water is 32 degrees Fahrenheit, 0 degrees Celsius, and 273.15 Kelvin.

How does this compare with the heat of the same temperature of water for the same temperature difference for water C 4190 J kg <UNK> <UNK> C?

How does this compare with the heat needed to raise the temperature of the same mass of water through the same temperature difference? Raising the temperature of 10 kg of steel by one degree takes 10kg(450 J/kg ⋅°C) = 4500 J. Raising it through 100 degrees takes 100 times as much, or 450,000 J.

Which has more heat energy?

Temperature is the average kinetic energy of particles of an object. Warmer objects have faster particles and higher temperatures. If two objects have the same mass, the object with the higher temperature has greater thermal energy.
