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.
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
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.
Answer:
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Explanation:
Answer:
Articular articular cartilage is very important part of the long bone structure. It is present between the bones at the joints and help in reducing the friction between the joints. the epiphytes is data present at the end of the long bones are usually have a covering of the articular cartilage and it has a very thin layer of cartilage that helps in reducing the friction .
It also act as a shock absorber between the two bones and helps in the transmission of force from one phone to another and divide the force across the skeletal system. It also transmit the force on the bones with low fictional coefficient. The articular cartilage are very susceptible and prone to the injury and it lacks blood vessels and nerves. Articular cartilage is made up of hyaline cartilage and is made up of densely packed extracellular matrix which certain type of specialised cells known as chondrocytes. It is also made up of water , collagen , proteoglycans and glycoproteins .
