Transcribed Image Text:A 30.0g piece of metal is heated to 95.0 °C. The metal is then placed into 45.0 grams of
water at 22.0 °C. If the final temperature of the water is 25.0 °C, thent what is the
specific heat of the metal, in J/g °C?
Expert Solution
Step 1
When the heated metal is dipped in water, then heat lost by metal goes to water.
Mass of metal= 30 g
Temperature change, T =(95 - 25)°C
Mass of water=45.0 g
Temperature change, T =(25 - 22)°C
Specific heat of water=4.184 J/g°C
