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

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
