8) Granite has a specific heat of 800.00J/gºC. What mass of granite is needed to store 150,000.00J
of heat if the temperature of the granite is to be increased by 15.5°C?

Need answer ASAP

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 .

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

which three statements are true about all alloys?
