Astudent using a styrofoam cup as a calorimeter added a piece of metal to distilled water and stirred the mixture. a) the initial temperature of 50.0 g of water was 25°c b) the initial temperature of 20.0 g of metal was 100 °c c) the final temperature of the water and metal was 32.0° c which statement correctly describes the heat flow in calories? [hint: ignore heat gained or lost by the calorimeter. no calculations are needed to be performed]
a. the water lost 1360 calories of heat and the metal gained 140 calories of heat.
b. the water lost 350 calories of heat and the metal gained 350 calories of heat.
c. the water gained 350 calories of heat and the metal lost 350 calories of heat.
d. the water gained 1360 calories of heat and the metal lost 350 calories of heat.
