The specific heat of a substance varies as (3t^2 + t) × 10^-3 cal g^-1 °C^-1, where 't' is temperature. The amount of heat required to raise the temperature of 1 kg of substance from 10°C to 20°C is...

Step 1
In this case, the mass m is 1 kg = 1000 g (since 1 kg = 1000 g), and the change in temperature ΔT is 20°C - 10°C = 10°C. The specific heat c is not constant, but varies with temperature as (3t^2 + t) × 10^-3 cal g^-1 °C^-1. Show more…
