The specific heat of silver is 0.234 j / (g·c). calculate the amount of energy that is needed to raise the temperature of 175 g of silver from 22.5°c to 40.0°c.

Heat energy is supplied to materials and can cause an increase in temperature of the material. the formula is as follows

H = mcΔt

where H - heat energy

m - mass of material

c - specific heat

Δt - change in temperature - 40.0 °C - 22.5 °C = 17.5 °C

substituting the values

H = 175 g x 0.234 Jg⁻¹°C⁻¹ x 17.5 °C

H = 716.6 J

716.6 J is required
