Question

Calculate the heat energy required to heat 10g of metal from 100⁰c to 150⁰c

Answer 1

Explanation:

500⁰c..............

Answer 2

The required heat energy is 500c Joules.

Given - Mass and change in temperature

Find - Heat energy

Solution - The heat energy can be calculated by the formula-

Q = m×c×∆t, where Q represents heat energy, m represents mass, c refers to specific heat capacity and ∆t is the change in temperature

Calculating ∆t

∆t = 150 - 100

Performing subtraction to find the change in temperature

∆t = 50° C

Keep the values in formula to find the value of heat energy required.

Q = 10×c×50

Performing multiplication to find the heat energy required

Q = 500c

Hence, the heat energy required is 500c Joules.
