Chapter 14: Problem 66

If the maximum intensity of radiation for a blackbody is found at $2.65 \mu \mathrm{m},$ what is the temperature of the radiating body?

Short Answer

Expert verified
Answer: The temperature of the radiating body is approximately 1094.34 K.

Step by step solution

01

Convert wavelength to meters

We are given \(\lambda_{max}\) in micrometers. Let's convert it to meters: $$\lambda_{max} = 2.65 \, \mu \mathrm{m} = 2.65 \times 10^{-6} \, \mathrm{m}$$
02

Rearrange Wien's Displacement Law formula

Let's rearrange Wien's Displacement Law formula to find the temperature \(T\): $$ T = \frac{b}{\lambda_{max}}$$
03

Plug in the values and solve for T

Now we will plug in the values for \(\lambda_{max}\) and \(b\) and solve for the temperature: $$ T = \frac{2.898 \times 10^{-3} \, \text{m K}}{2.65 \times 10^{-6} \, \mathrm{m}}$$ Divide \(2.898 \times 10^{-3}\) by \(2.65 \times 10^{-6}\) to find the temperature: $$ T \approx 1094.34 \, \text{K}$$ So, the temperature of the radiating body is approximately \(1094.34 \, \text{K}\).

A mass of \(1.4 \mathrm{kg}\) of water at \(22^{\circ} \mathrm{C}\) is poured from a height of \(2.5 \mathrm{m}\) into a vessel containing \(5.0 \mathrm{kg}\) of water at \(22^{\circ} \mathrm{C} .\) (a) How much does the internal energy of the \(6.4 \mathrm{kg}\) of water increase? (b) Is it likely that the water temperature increases? Explain.
A piece of gold of mass \(0.250 \mathrm{kg}\) and at a temperature of \(75.0^{\circ} \mathrm{C}\) is placed into a \(1.500-\mathrm{kg}\) copper pot containing \(0.500 \mathrm{L}\) of water. The pot and water are at $22.0^{\circ} \mathrm{C}$ before the gold is added. What is the final temperature of the water?
Convert \(1.00 \mathrm{kJ}\) to kilowatt-hours \((\mathrm{kWh})\).
Imagine that 501 people are present in a movie theater of volume $8.00 \times 10^{3} \mathrm{m}^{3}$ that is sealed shut so no air can escape. Each person gives off heat at an average rate of \(110 \mathrm{W} .\) By how much will the temperature of the air have increased during a 2.0 -h movie? The initial pressure is \(1.01 \times 10^{5} \mathrm{Pa}\) and the initial temperature is \(20.0^{\circ} \mathrm{C} .\) Assume that all the heat output of the people goes into heating the air (a diatomic gas).
