Answer 2

Assuming you're asking for the value of the kinetic energy (Ek) of a particle at a temperature of 17 degrees Celsius (T=17°C) with the Boltzmann constant (k) equal to 1.38 × 10^-23 J/K, we can use the following formula:

Ek = (1/2) * k * T

Where:

• Ek is the kinetic energy in Joules (J)
• k is the Boltzmann constant (1.38 × 10^-23 J/K)
• T is the temperature in Kelvin (K)

First, we need to convert the temperature from Celsius to Kelvin:

T (K) = T (°C) + 273.15 T (K) = 17°C + 273.15 T (K) = 290.15 K

Now we can plug in the values into the formula:

Ek = (1/2) * k * T Ek = (1/2) * 1.38 × 10^-23 J/K * 290.15 K Ek = 1.99 × 10^-21 J

Therefore, the kinetic energy of a particle at 17°C with the given Boltzmann constant is approximately 1.99 × 10^-21 J.
