Question

How much heat will a 45.00 g piece of glass require to change its temperature from 10 to 30 °C. The specific heat capacity is 0.500 J/g°C.
675 J

225 J



450 J


700 J

Answer 1

Answer:

Q = 450 J

Explanation:

Given that,

Mass of a piece of glass, m = 45 g

The temperature changes from 10°C to 30°C.

The specific heat is 0.5 J/g°C

We need to find heat required to raise the temperature. The formula that is used to find it is given by :

$Q=mc\Delta T\\\\Q=45\times 0.5\times (30-10)\\\\Q=450\ J$

So, the required heat is 450 J. Hence, the correct option is (c).
