Answer:

Q = 450 J

Step-by-step 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* 0.5* (30-10)\\\\Q=450\ J

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