What will be the change of temperature for 300 gr of iron (Fe) which have gained 2000 cal?
For a thermodynamic system, isobaric coefficient of volume expansion (a) and isothermal compressibility (b) are defined as
a=(1/v) (dv/dT)p b= -(1/v) (dv/dp)T
Show that for an isochoric change, b dp = a dT.
The energy given off as heat by 300g of an alloy as it cools through 50OC raises the
temperature of 300g of water from 30OC to 40 OC. What is the specific heat of the alloy (in
cal/g· OC)?
Refer to “common misconception” box of the module and provide brief answer on why the statements
there are considered wrong.
What total heat is released when 0.500 lb of steam at 212°F changes to ice at -6°F?
What quantity of heat is needed to convert 2 kg of ice at -34°C to steam at 100°C?
(a) the final volume of the gas
(b) the work done on the gas, hence, find the energy transffered by heat.
(a) the temperature of the gas doesn't change
(b) Work is done on or by the gas
(c) No energy is transferred by heat to or from the gas.
(d) The volume of the gas remains the same.
