Question

The equation below can be used to find the specific heat capacity of a substance. What is the specific heat capacity if it takes 1000 J of energy to heat 25 g of this substance by 100°C? Give your answer in J/kg°C.

Answer 1

Answer:

0.4j/g

Explanation:

• using H = MCQ

where H is heat energy, M is mass of substance, and Q temperature change

• 1000= 25*C*100
• 1000=25*100*C
• 1000=2500C
• divide both by 2500
• 1000/2500=C
• C = 0.4j/g
