these steps are involved in the production of work by a four-stroke heat engine. place the steps in the correct order.

piston moves up, compressing gas and causing gas to increase its temperature:

piston moves up, pushing burned gases through exhaust valve:

spark plug fires, causing combustion as gas is still compressed; increase in energy from combustion pushes piston down:

piston moves down, allowing fuel-air mixture to enter intake valve:

Explanation:

There are four basic steps of a four stroke engine- Intake, Combustion, Power and Exhaust. The first step is the intake of air plus fuel mixture in the combustion chamber. At this time, the piston moves down. Now when the chamber is closed, the spark plug ignites fire which expands the fuel gases.

The gases push down, piston and crankshaft rotates in this way. Once the gases the combustion is done, there is plenty of space in the chamber that makes the piston moves up. In this way a complete cycle is completed and the crankshaft moves. That’s the working of this four stroke engines.

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds
