Question

Which requires more heat to warm from 22.0°C and 85.0°C, 45.0 g of water or 200. g of aluminum metal?

water
aluminum

What is the heat produced in each case? Use 0.905 J/cal°C for Al.

water
______ J

Aluminum
______ J

Answer 1

The answer to your question is Aluminum

Step-by-step explanation:

We need to warm from 22°C to 85°C

a) 45 g of water

b) 200 g of aluminum Cp = 0.905 J/cal°C

a) Water

Q = mCpΔT

Q = (45)(1)(85 - 22) = 45(63) = 2835 cal

b) Aluminum

Q = (200)(0.905)(85 - 22) = 114030 cal
