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?
stich3 [128]

Answer:

The answer to your question is Aluminum

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

The equation, DF + heat Imported Asset D + F, is an example of an endothermic reaction.
zvonat [6]
The answer is TRUE.

If the Energy is on the left, then the problem is true. If it is on the right then it would be negative, false, and considered as exothermic.

Endothermic reaction = the products are higher in energy than the reactants.
Exothermic reaction = a chemical reaction that releases energy by light or heat.
