(a)(i) Sketch a graph to illustrate Charles’ law.
(ii) A gas occupies 500 cm(^{ 3}) at 2TC. calculate its volume at 40°C constant pressure.
(b) List two gases that are used as refrigerant
Explanation
(a)(i)
(ii) (frac{v}{T} = frac{v}{T})
(frac{500}{300} = frac{v}{313})
(v_2 = frac{500 times 313}{300})
(v_2 = frac{500 times 313}{300})
(v_2 = 522cm^3)
(b) Two gases that are used as refriger are;
(i) Ammonia (NH(_3)) and
(ii) Carbon dioxide (CO(_2))
