Energy from the Sun is released by nuclear fusion - AQA - GCSE Physics - Question 2 - 2021 - Paper 1

To calculate the energy required, we can use the formula:

$E = mc heta$

Where:

• $m$ = mass of deuterium = 0.004 kg
• $c$ = specific heat capacity = 5200 J/kg °C
• $heta$ = temperature change = 50 000 000 °C

Substituting the values into the equation gives:

$E = 0.004 imes 5200 imes 50 000 000 = 1.04 imes 10^9 ext{ J}$

1. To make sure the fusion process is possible.
2. To assess the efficiency of the process.

Generating electricity using fossil fuels releases carbon dioxide, which causes global warming.

Generating electricity using fossil fuels releases sulfur dioxide, which causes acid rain.
