Besides Joule's classic experiment, another way of demonstrating the equivalence between mechanical energy and heat is the following: Put some lead shot into a glass tube, seal both ends of the tube, invert the tube quickly several times, and measure the temperature of the shot. If you assume that all the mechanical energy is converted into heat in the lead shot and that no heat is lost, what is the change in the temperature of the shot if the tube is 1 m long, there are 14 g of shot, and the tube is inverted 8 times? (The specific heat of lead is 0.128 kJ/kg - K.)

A bullet made of silver (specific heat 234 J/kg deg C) traveling at 380 m/s hits a wooden post and stops. If 39% of the kinetic energy of the bullet becomes heat trapped in the bullet, what is the temperature change (in deg C) of the bullet? (Hint: you do not need the mass of the bullet, it cancels out)
Use the given data below to find the calculated amount of heat transferred and the final calculated temperature of the system. Mass of hot water= 110g Temperature of hot water= 90°C Mass of cold water = 130g Temperature of cold water= 20°C Final temperature of the system from the simulator= 52.08°C Specific heat= 4.184 J/g x °C
Satellites designed to observe the radiation from cold (3 K) dark space have sensors that are shaded from the Sun, Earth, and Moon and that are cooled to very low temperatures. Why must the sensors be at low temperature?
The amount of heat is often measured in calories. If I add 3 calorie of heat energy to 1 gram of water, the temperature of the water will decrease by 1° stay the same, since water has a very high specific increase by 3° increase by 3° decrease by 2°C
The figure below, called a heating curve, represents the temperature of a block of ice as thermal energy is added. (The ice melts into water and then vaporizes into steam.) The thermal energy required to change phase from solid to liquid is calculated using the equation Q = mLf, where Lf is called the (latent) heat of fusion. The thermal energy required to change phase from liquid to gas is calculated using the equation Q = mLv, where Lv is called the (latent) heat of vaporization. cice = 2100 J/kg·K; cwater = 4186 J/kg·K; csteam = 2000 J/kg·K; Lf of water = 3.33 x 105 J/kg; Lv of water = 2.26 x 106 J/kgA snowball made of ice at -11.2 degrees Celsius is thrown at a brick wall. Assuming no energy is lost to the wall or surrounding air, how fast would the snowball have to be thrown in order to completely vaporize upon impact? Include units in your answer. More information.

When you turn your hot water on in the shower, it takes a bit for the water to get warm. Some of this is because the water in the pipe is cold but some of it is because the water from the hot water heater must heat the copper plumbing pipe itself. Copper has a specific heat of 0.39R. How much energy does it take to heat 2 kilograms of copper pipe from 70°F to 130°F? Report your answer in Joules. (Hint: Note that you'll need to convert kJ to J and F to K.)
Beryllium has roughly one-half the specific heat of liquid water (H20). Rank the quantities of energy input required to produce the following changes from the largest to the smallest. In your ranking, note any cases of equality.
