After an electric sign is turned on, the temperature of its glass goes from 23.5°C to 65.5°C. The sign’s glass has a mass of 905 grams, and the specific heat capacity of the glass is 0.67 joules/gram degree Celsius. How much heat did the glass absorb? Type the correct answer in the box. Use numerals instead of words. Express your answer to the correct number of significant figures.

The sign's glass absorbed 25466.7 J

Further explanation

Given

The temperature of glass :  23.5 °C to 65.5 °C

mass = 905 g

the specific heat capacity = 0.67 J/g °C

Required

Heat absorbed

Solution

Heat absorbed by sign's glass can be formulated :

ΔT=65.5 - 23.5 = 42

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
