A gas is currently at a temperature of 84º C at a volume of 10 liters. If the pressure is kept the same and the temperature is lowered to 72º C, what will the new volume be?

9.66 L

Explanation:

The following data were obtained from the question:

Initial temperature (T1) = 84 ºC

Initial volume (V1) = 10 L

Final temperature (T2) = 72 ºC

Final volume (V2) =..?

Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T1) = 84 ºC

Initial temperature (T1) = 84 ºC + 273 = 357 K

Final temperature (T2) = 72 ºC

Final temperature (T2) = 72 ºC + 273 = 345 K

Since the pressure is constant, it means the gas is obeying Charles' law. Thus, we shall determine the new volume of the gas as follow:

Initial temperature (T1) = 357 K

Initial volume (V1) = 10 L

Final temperature (T2) = 345 K

Final volume (V2) =..?

V1/T1 = V2/T2

10/357 = V2/345

Cross multiply

357 × V2 = 10 × 345

Divide both side by 357

V2 = (10 × 345) / 357

V2 = 9.66 L

Thus, the new volume of the gas is 9.66 L.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
