A 7.70-kg steel ball at 18.7°C is dropped from a height of 12.7 m into an insulated container with 4.50 L of water at 10.1°C. If no water splashes, what is the final temperature of the water and steel? The specific heat of steel and water is 450 J/(kg·K) and 4186 J/(kg·K) respectively.
How much internal energy is generated when a 19.8-g lead bullet, traveling at 7.80 × 102 m/s, comes to a stop as it strikes a metal plate?
A system takes in 0.380 kJ of heat while it does 0.790 kJ of work on the surroundings. What is the change in internal energy of the system?
A hyperthermic (feverish) male, with a body mass of 104 kg, has a mean body temperature of 107F. He is to
be cooled to 98.6F by placing him in a water bath, which is initially at 77F. Calculate what is the minimum
volume of water required to achieve this result. The specific heat capacity of a human body is 3.5 kJ/(kg·K). The
specific heat capacity for water is 4186 J/(kg·K). You must first find an appropriate formula, before substituting
the applicable numbers.

A monatomic ideal gas at 27.0°C undergoes a constant volume process from A to B and a constant-pressure process from B to C.
where P1 = 2.70, P2 = 5.40, V1 = 2.70, and V2 = 5.40.
Find the total work done on the gas during these two processes.
What is the total thermal energy of 1 mol of an ideal monatomic gas at a temperature of 0°C?
On a linear X temperature scale, water freezes at -125.00X and boils at 375.00 X.
On a linear Y temperature scale, water freezes at -70.000 Y and boils at -30.000
Y. A temperature of 50.000 Y corresponds to what temperature on the X scale?
