I think you divide so 2 sorry I’m wrong
Answer:
Decrease the number of gas particles, increase the object's area, and reduce the temperature of the gas
Explanation:
<u>TEMPERATURE</u>:
Decreasing the temperature will slow down the molecules. Hence, less no. of collisions will take place between walls of object and molecules. This will result in decrease of pressure.
Therefore, the pressure of a gas can be decreased by increasing its temperature.
<u>NUMBER OF GAS PARTICLES</u>:
Decreasing the number of particles will result in less no. of collisions, hence decreasing the pressure.
Therefore, the pressure of a gas can be decreased by decreasing its no. of molecules or no. of particles.
<u>AREA OF OBJECT:</u>
The pressure is given by the formula:
where,
A = Area of Object
Therefore, the pressure of a gas can be decreased by increasing area of object.
So, the correct option is:
<u>Decrease the number of gas particles, increase the object's area, and reduce the temperature of the gas</u>
Explanation:
Since P=W/t
P= 40000/20
P= 2000 Watt(or)Joule per sec
Answer: I only have the answer for A, but still, the answer is 20.07.
- Explanation: Because the number ends in a 15, round to the nearest tenth which is 20. So now the number is 5420.
- To get the Watts (W) you have to take 5420 and divide it by the time in seconds. 4.5 minutes in seconds is 270, so 5420 divided by 270 equals 20.07.
- So 20.07 is the answer.
