Question

How much heat is released when 10.0 grams of a substance cools 15 degrees? The specific

heat of the substance is 3.5 J/g °C.

Answer 1

Q = 525 J

Step-by-step explanation:

Given that,

Mass, m = 10 grams

The change in temperature,
`\Delta T=15^(\circ) C`

The specific heat of the substance is 3.5 J/g °C

We need to find the amount of heat released in the process. It can be given by the formula as follow :

`Q=mc\Delta T\\\\Q=10\ g* 3.5\ J/g^(\circ) C* 15^(\circ) C\\Q=525\ J`

Hence, 525 J of heat is released.
