Answer to Question #295496 in Molecular Physics | Thermodynamics for fsts

Question

A 1-kg metal sample is heated to 90°C and then dropped into an insulated container containing 200 mL of water at 25°C. When thermal equilibrium is reached, the temperature of water rose to 40°C. What is the final temperature of the metal sample?

Answer 1

M=1kg

T=90°C

T=25°C

T_s =40°C

thermal equilibrium is reached, the temperature of water rose to 40°C

T=40°C

Remain same final temperature of matel sample as well asT=40°C
