How much heat is required to raise the temperature of a 55 g glass ball by 16°c?

When an object gets heated by a temperature ΔT energy needed, E = mcΔT

Here mass of glass = 55 g =

  Change in temperature  ΔT  = 16^0C[/tex] = 16 K

  Specific heat of glass = 0.84 J/gK = 840 J/kgK

  Substituting we will get

            E = *840*16 = 739.2 J

So a heat of  739.2 J is required to raise the temperature of a 55 g glass ball by 16°C

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
