Question

What is the final temperature of a sample of magnesium (c = 0.24 cal/g°C), if 1835 cal is
added to 612 g of magnesium at an initial temperature of 19.3°C?

Answer 1

Answer:31.8 °C

Explanation:

Delta T=?

C= .24 cal/g°C

M=612g

Q=1835

Delta T= 1835 cal/(.24cal/g°C)(612g)=12.50°C

Intial temp= 19.3°C

Add intial temp to new temp

12.50+19.3=31.8°C
