Short Answer

How is heat transfer related to temperature?

Heat transfer is the spontaneous energy transformation that occurs due to the change in temperature.

Step by Step Solution

TABLE OF CONTENTS :
TABLE OF CONTENTS

Step1:Define heat transfer

Heat transfer is the transfer of energy due to a difference in the temperatures. Heat transfer between two bodies continues until the temperatures of both bodies become equal. It is a spontaneous energy transfer that results from the change in temperature.

Step 2: Describe the relation between heat transfer and temperature

Heat transfer is directly proportional to the mass of a substance, its specific heat capacity, and the difference in temperature. It is mathematically expressed as;

\({\rm{Q = mc\Delta T}}\)

Here, \({\rm{Q}}\) is the amount of heat transfer, \({\rm{m}}\) is the mass of the substance, \({\rm{c}}\) is the specific heat capacity, and \({\rm{\Delta T}}\) is the difference in temperature.

So, the amount of heat transfer increases with the rise of the difference in temperature.

On average, would Earth be warmer or cooler without the atmosphere? Explain your answer.

The brakes in a car increase in temperature by \({\bf{\Delta T}}\) when bringing the car to rest from a speed \(v\). How much greater would \({\bf{\Delta T}}\) be if the car initially had twice the speed? You may assume the car to stop sufficiently fast so that no heat transfers out of the brakes.

Freeze-dried foods have been dehydrated in a vacuum. During the process, the food freezes and must be heated to facilitate dehydration. Explain both how the vacuum speeds up dehydration and why the food freezes as a result.

Why are thermometers that are used in weather stations shielded from the sunshine? What does a thermometer measure if it is shielded from the sunshine and also if it is not?

A large body of lava from a volcano has stopped flowing and is slowly cooling. The interior of the lava is at 1200ºC , its surface is at 450ºC , and the surroundings are at 27.0ºC . (a) Calculate the rate at which energy is transferred by radiation from \({\bf{1}}{\bf{.00 }}{{\bf{m}}^{\bf{2}}}\) of surface lava into the surroundings, assuming the emissivity is 1.00. (b) Suppose heat conduction to the surface occurs at the same rate. What is the thickness of the lava between the 450ºC surface and the 1200ºC interior, assuming that the lava’s conductivity is the same as that of brick?
