Gas temperature remains at a higher average with increased speed.

When the spark advance is same as the optimum value the heat rejected to cooling system is increased.

In the case of water cooling, there no boundary layer of the liquid coolant on the outside of the cylinder wall.

In the case of air cooling, the boundary layer as on the gas side offers great resistance, but the effect of this is compensated largely by providing more surface areas by way of cooling pins.

____________ is the transfer of heat through space or matter by means other than conduction or convection.

When the work is done to blow or pump the fluid, it is said to be ____________ convection.

In natural convection, the denser portions of the fluid move downward because of the greater force of gravity, as compared with the force on the less dense.

____________ convection occurs when the fluid circulates by virtue of the natural differences in densities of hot and cold fluids.

____________ is the transfer of heat within a fluid by mixing of one portion of fluid with another.

____________ is the transfer of heat from one part of a substance to another part of the same substance.
