One liter of gas is measured out at 37 degree Celsius at a constant pressure . What volume will it occupy at -25 degree Celsius

0.8 L

Explanation:

Ideal gas law: PV = nRT

At constant mass and pressure, nR/P = nR/P.

Therefore, V/T = V/T.  (Remember to use absolute temperature.)

V/T = V/T

1 L / (37 + 273 K) = V / (-25 + 273 K)

V = 0.8 L

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
