Q1:

Thermal efficiency of an internal combustion engine is around __________ percent.

A 8

B 35

C 65

D 80

ANS:B - 35

The thermal efficiency of an internal combustion engine typically ranges from about 25% to 30% for gasoline engines and from about 30% to 40% for diesel engines. Therefore, the closest option among the ones provided would be 35%. However, it's important to note that the actual thermal efficiency can vary based on factors such as engine design, operating conditions, fuel quality, and maintenance.
