What is temperature? What is heat?
Definitions of temperature and heat.
Answer to Problem 1CQ
Temperature is a measure of the average kinetic energy of the molecules that constitute a substance and the measure of the internal energy that is absorbed or transferred from one body to the other is termed as heat.
Explanation of Solution
Temperature is a measure of the average kinetic energy of the molecules that constitute a substance. It measures how much hot or cold a material is. The scales in which the temperature is measured are the Kelvin Scale
The measure of the internal energy that is absorbed or transferred from one body to the other is termed as heat. The transfer of energy within a body or from one body to the other is called heat transfer. There are three modes by which heat can get transferred from one body to the other namely conduction that is by the molecules vibrating about their axis; convection that is by the movement of molecules from one place to the other and radiation that involve the use of waves.
Conclusion:
Therefore, the temperature measures the average kinetic energy of the molecules that constitute a substance and the measure of the internal energy that is absorbed or transferred from one body to the other is termed as heat.

- Compare the SI units of specific heat and latent heat and explain any differences.arrow_forwardThe Fahrenheit scale remains useful in part due to personal experience with temperature. For example, the average temperature range in a typical midlatitude city such as Gdansk, Poland (formerly Dansk, where Fahrenheit was born), is 25F to 78F over a year. a. Find the temperature range in Gdansk, Poland, in degrees Celsius and in kelvins. b. Many people say that 0F is a very cold day and 100F is an unpleasantly hot day. Convert these temperatures to the Celsius and Kelvin scales. c.When someone has an infection, her body may respond with a fever. A high fever (T 105F) can damage the brain. Convert this temperature to degrees Celsius.arrow_forwardWhat are the following temperatures on the Kelvin scale? (a) 68.0 F, an indoor temperature sometimes recommended for energy conservation in winter (b) 134 F, one of the highest atmospheric temperatures ever recorded on Earth (Death Valley, California, 1913) (c) 9890 F, the temperature of the surface of the Sunarrow_forward

- The mass of a hot-air balloon and its cargo (not including the air inside) is 200 kg. The air outside is at 10.0C and 101 kPa. The volume of the balloon is 400 m3. To what temperature must the air in the balloon be warmed before the balloon will lift off? (Air density at 10.0C is 1.244 kg/m3.)arrow_forwardHow does the latent heat of fusion of water help slow the decrease of air temperatures, perhaps preventing temperatures from falling significantly below 0C, in the vicinity of large bodies of water?arrow_forward
