its not, not necessary
Through direct contact of particles
Conduction. In this process, heat energy is transferred through direct contact between the material being heated and the heat source.
The O2 heated sensor on a 2005 Chevrolet Aveo is located in the exhaust manifold. It measures the amount of oxygen left in the exhaust gases as they leave the vehicle.
Air is heated by conduction when it comes into direct contact with a warmer surface, such as the ground or a heated object. The heat energy is transferred from the surface to the air molecules through direct contact, causing the air molecules to gain kinetic energy and move faster, increasing the air temperature.
To find out, he took a culture of these cells, heated the bacteria to kill them, and injected the heat-killed bacteria into the mice. The Mice survived, suggesting that the cause of pneumonia was not a chemical poison released by the disease-causing bacteria.
casting is that in which the metal melts in liquid form by heating and drawn in the mould. after some time it takes a shape of mould. forging is that in which the metal heated (at that point in which it is in a solid form) and took the shape by hammering, punching, pressing etc.
its on the intake manifold one right side of air cleaner it is a heated pcv valve it has wires goin to it
there are actually 2 sensors on a 1998 s10 2.2l one is on the exhaust manifold and the other is downstream of the catalytic converter, but unfortunately i don't know which ones are heated. i read somewhere that all knew o2 sensors are heated. If the sensor has 4 wires feeding it, it is heated, 2 wires, it is not. As previously mentioned most 02 sensors are heated now.
During the day, the land is heated mainly by the sun's radiation warming the surface. The air is heated through conduction from the warm surface of the Earth. Water is heated through a combination of direct solar radiation and convection currents transferring heat energy.
The heated coolant comes out of the engine from the connection in the intake manifold and returns thru the connection into the water pump.
In chemistry, a ring stand places a heated sample above the direct flame of a Bunsen burner.
