Suppose you have a piston in a cylinder where the gas temperature is 26.0° C and has a volume of 1.75 L. What is the volume of t
blsea [12.9K]

Answer:

1.62 L

Explanation:

Charle's law for ideal gases states that for a gas kept at constant pressure, the ratio between volume and temperature is constant:

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where in this problem we have

V_1 = 1.75 L is the initial volume of the gas

T_1 = 26.0^{\circ}+273=299 K is the initial temperature of the gas

V_2 is the final volume of the gas

T_2 = 3.0^{\circ}+273=276 K is the final temperature

Solving the equation for V2, we find

V_2 = \frac{V_1}{T_1} T_2 = \frac{1.75 L}{299 K}(276 K)=1.62 L

Is the energy of a wave is calculated by squaring the frequency of the wave?
Misha Larkins [42]
Nope.
Energy is directly proportional to frequency. and when you calculate energy, you multiply frequency with a constant number called "Planck's Constant"

E = hf

Hope this helps!
