Q1. How much ice at a temperature of -12.10 rm {^ {circ} C} must be dropped into the water so that the final temperature of the system will be 35.0rm {^ {circ} C}?
Q2. The rms speed of the molecules in 1.70 g of hydrogen gas is 1700m/s.
A) what is the total translational kinetic energy of the gas molecules?
B) What is the thermal energy of gas?
C) 300 J of work are done to compress the gas as, in the same process, 1200 J of heat energy are transferred from the gas to the environment. Afterward, what is the rms speed of the molecules?
