The temperature of the sun's interior is estimated to be about 14 × 1 0 6 K. Protons ( m = 1.67 × 1 0 − 27 kg) compose most of its mass. Compute the average speed of a proton by assuming that the protons act as particles in an ideal gas.

v r m s = m 3 k T = 1.67 × 1 0 − 27 3 × 1.38 × 1 0 − 23 × 1.4 × 1 0 7 = 5.89 × 1 0 5 m s − 1 .

The temperature of the sun's interior is estimated to be about $14 \times 1 0^{6}$ K. Protons ( $m = 1.67 \times 1 0^{- 27}$ kg) compose most of its mass. Compute the average speed of a proton by assuming that the protons act as particles in an ideal gas.

Answer:

589000

Solution:

$v_{r m s} = \frac{3 k T}{m} = \frac{3 \times 1.38 \times 1 0 ^{- 23} \times 1.4 \times 1 0 ^{7}}{1.67 \times 1 0 ^{- 27}} = 5.89 \times 1 0^{5}$ m $s^{- 1}$ .
