Consider three 2.50-liter flasks at 480 Torr and 371 K. Flask A contains SF6 gas, flask B contains N2 gas and flask C contains CH4 gas. In which flask do the molecules have the highest average kinetic energy

A155.0 9 piece of copper at 182 °c is dropped into 2500 g of water at 23.9 °c. (the specific heat of copper is 0.385 1/9°c.) calculate the final temperature of the mixture. (assume no heat loss to the surroundings.)
