Question

for each pair of substances, circle the substance with more thermal energy and explain why? A0 500g of water at 35 degree C VS. 500 g of water at 85 degree C

B) 500 g of water at 35 degree C VS. 250 g of water at 35 degree C

Answer 1

A) Since the masses are equal, there is more thermal energy in the hotter water.

B) Since they are at the same temperature, there is more total thermal energy in the larger mass, 500 g.

Temperature measures thermal energy per mass

Answer 2

500 g of water
Same temperature if you have more water it takes more energy to heat up
