# What is the heat change if 254 g of solid gold increases in temperature by 20 K to 1 d.p?(The molar heat capacity of solid gold is 25.42 J mol-1 K-1)

## Question

## Solution 1

To calculate the heat change, we can use the formula for heat change which is:

q = mcΔT

where: q = heat change m = mass c = specific heat capacity ΔT = change in temperature

However, we are given the molar heat capacity and the mass, so we first need to convert the mass of gold to moles. The mola Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
