Question

A balloon contain 1000 kg of air. If its tem-
perature is changed by 60°C then find
change in thermal energy of air
(1) 41570 kJ (2) 43152 kJ
(3) 44000 kJ (4) 46121 kJ
​

Answer 1

Answer:

In an ic engine intake temperature increases then the efficiency of engine is. If the intake temperature increases the efficiency will decrease... Because if the intake temperature increases the density of the air will reduce...by increasing the density of the intake of intake air only we can increase the efficiency..
