The volume of a gas varies directly with its temperature and inversely with the pressure. If the volume of a certain gas is 15 cubic feet at a temperature of 300 K and a pressure of 40 pounds per square inch, what is the volume of the same gas at 320 K when the pressure is 20 pounds per square inch?

Therefore the volume of the gas is 32 cubic feet.

Step-by-step explanation:

Given that,

The volume of a gas varies directly with its temperature and inversely with the pressure.

V= Volume of the gas at constant mass

T= Temperature at constant mass

P= pressure at constant mass

.

Given that,

At constant mass, the volume of a certain gas is 15 cubic feet and a pressure of 40 pound per square inch at a temperature 300 k.

=15 cubic feet, =40 pound per square inch and = 300 K

, =20 pound per square inch and = 320k

.

Plugging all values

cubic feet

Therefore the volume of the gas is 32 cubic feet.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
