Hi Н ШICI КОН EtOH Heat

) How much heat must be applied to a 40.2-g sample of gold (s = 0.129 J/(g ∙ °C)) inorder to raise its temperature from 28.2°C to 351.5°C?a. 1.82 × 103 Jb. 1.68 × 103 Jc. 1.46 × 102 Jd. 1.3 × 104 Je. 4.17 × 101 J

The specific heat of a certain type of metal is 0.128 J/(g⋅∘C). What is the final temperature if 305 J of heat is added to 70.2 g of this metal, initially at 20.0 ∘C? ?final=                                  ∘C

A 130.3 g piece of copper (specific heat 0.38 J/g･°C) is heated and then placed into 400.0 g of water initially at 20.7°C. The water increases in temperature to 22.2°C. What is the initial temperature (in °C) of the copper? (The specific heat of water is 4.18 J/g･°C).
