200 gr of water in a thermally insulated container. 200 gr of water is initially at 25 o C in a thermally insulated calorimeter. a) If 50 gr of ice at –15 o C is dropped into this calorimeter what is the final temperature after thermal equilibrium is established. b) If Instead 300 gr of ice at –30 o C is added how much ice will remain when equilibrium is reached? c) In part (a) what is the change in...
1.) 40 g of liquid water at 30 C and 20 g of ice at 0 C are mixed together in an insulated container. Assuming there is not heat lost to surroundings, what will the temperature be when the mixture has reached thermal equilibrium. (show your work) 2.)20 g of ice at 0 C and 10 g of steam at 100 C are mixed together in an insulated container. Assuming there is not heat lost to surroundings, what will the...
