4. How much work is done by or on the system (state which), in KJ, in...
1. a) How much work is done by/on the system when is taken from
point a to point b following the
path indicated in the figure?
b) How much heat is absorbed/released by the system when is
taken from point a to point b
following the path indicated in the figure? Express your answer in
kJ
c) What is the change in internal energy, ?U? Express your
answer in kJ.
2. a) How much work is done on the system...
If a system has 425 kcal of work done to it, and releases 5.00×102 kJ of heat into its surroundings, what is the change in internal energy (Δ? or Δ?) of the system?
heat in terms of kcals not kJ
How much heat is required to raise the temperature of 11.1 g of water from -45°C to 175 °C? heat: kcal
If a system has 375 kcal of work done to it, and releases 5.00 x 10 kJ of heat into its surroundings, what is the change in internal energy (AE or AU) of the system? - - AE = |
If a system has 4.50 x 102 kcal of work done to it, and releases 5.00 × 102 kJ of heat into its surroundings. what is the change in internal energy of the system? Number kJ
If a system has 3.50 x 102 kcal of work done to it, and releases 5.00 x 102 kJ of heat into its surroundings, what is the change in internal energy (AE or AU) of the system? AE=
If a system has 225 kcal of work done to it, and releases 5.00 × 10 2 kJ of heat into its surroundings, what is the change in internal energy ( Δ E or Δ U ) of the system?
How much heat (in kJ) is required to warm 175 g of sand from 25.0 oC to 75.0 oC ?
