Question

How much heat is required to raise the temperature of 5kg of iron from 50°c to250°c​

Answer 1

462000J

Step-by-step explanation:

Quantity of heat= mass x specific heat capacity of iron x change in temp

specific heat capacity of iron is 462J/Kg/K

change in temp = 250-50= 200°C

200°C is equivalent to 200K since 1°C is 1K

Q= mct

= 5x462x200

= 462000J
