Answer:
Explanation:
The formula for the heat released is
q = mCΔT
Data:
m = 28.9 g
C = 0.385 J·°C⁻¹g⁻¹
T₁ = 1083 °C
T₂ = 25.0 °C
Calculations:
(a)Temperature change
ΔT = T₂ - T₁ = 25.0 - 1083 = -1058 °C
(b) Heat released
q = 28.9 × 0.385 × (-1058) = -11 800 J = -11.8 kJ
The negative sign shows that energy is released, so the copper has released 
of energy.
There are many differences between ideal gas and real gas; some of the main differences are as following:
- An ideal gas follows the formula PV=nRT but a real gas does not always follow this formula.
- There is no attraction between the molecules of an ideal gas. A real gas has significant particle attractions.
- The particles of an ideal gas lose no energy to its container. A real gas conducts and radiates heat, thereby losing energy.
- An ideal gas is infinitely compressible, a real gas will condense to a liquid at some pressure.
- Real gas particles have a volume and ideal gas particles do not.
- Real gas particles collide in-elastically (loses energy with collisions) and ideal gas particles collide elastically.
