Explanation:
From the given information:
The equation connecting the photon energy and the wavelength is:
where;
= 6.626 * 10 ^{-34} J.s
= 3.00 * 10^8 m/s
wavelength
To determine the photon energy of violet light
= 4.847 × 10⁻¹⁹ J
Answer : The temperature of gas is, 295 K
Explanation :
To calculate the temperature of gas we are using ideal gas equation:
where,
P = Pressure of gas = 1.21 atm
V = Volume of gas = 10.0 L
n = number of moles = 0.500 mole
R = Gas constant =
T = Temperature of gas = ?
Now put all the given values in above equation, we get:
Therefore, the temperature of gas is, 295 K
