marysya [2.9K]

The dimensions of the room is not given. Lets assume a value and calculate BTU accordingly.

Answer and Explanation:

BTU, or British Thermal Unit, is defined as the amount of heat required to raise the temperature of 1 pound of water by 1° F.

In other words,BTU's measures the amount of heat an AC (or any other cooling unit) can remove from a room per hour. Higher the BTU, the more powerful the cooling.

Calculation:

Lets assume that a room is 10 feet wide and 14 feet long.

  • Step 1

Calculate the size of the room by multiplying the height of the room with its width:

size of the room= 10 × 14

                          = 140 square feet

  • Step 2

Then multiply the size of the room that you obtained in step 1 with 20 BTU per square foot, in order to get the minimum BTU's required for AC to cool a room,

140 × 20= 2800

 2800 BTU cooling capacity is required.

An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.

Fossil fuels are the fuels which are generated after a long time taking geological process over the buried organic matter obtain from dead animals, animal dung and plants. The organic matter remain under the heap of earth crust under intense heat and pressure. The heat and pressure generate fuels which are valuable for the entire society as when they are burned they produce huge amount of thermal energy. These includes the crude oil like petroleum, natural gas and coal.
