Question

8) Granite has a specific heat of 800.00J/gºC. What mass of granite is needed to store 150,000.00J

Answer 1

Answer:

Explanation:

specific heat of granite  S = 800 J /g°C

increase in temperature = 15.5 °C .

mass  = m ( let )

Heat needed to raise temp  = mass x specific heat x rise in temperature

150,000 = m x 800 x 15.5

m = 12.096 g .
