20. Heat and Temperature

Which of the following best describes the relationship between thermal energy and temperature?

When the temperature $T$ of a semiconductor increases, what happens to its electrical conductivity $\sigma$?

Which of the following has the most thermal energy?

When the temperature $T$ of a fluid increases, which of the following typically occurs?

Which of the following does a burner on a stove primarily produce?

When a warm hand is immersed in water that is $70°F$, what happens to the temperature of the hand over time?

When the temperature of matter decreases, which of the following typically occurs?

As you climb to higher altitudes in the troposphere, what generally happens to the air temperature?

How does altitude affect temperature in different latitudes?

What is temperature a measure of?

The tungsten filaments inside of most incandescent lightbulbs reach temperatures of about 4580°F when the lightbulbs are lit. What is this temperature in a) Celsius and b) Kelvin?

Like the Kelvin scale, the Rankine scale is an absolute temperature scale: Absolute zero is zero degrees Rankine (0°R). However, the units of this scale are the same size as those of the Fahrenheit scale rather than the Celsius scale. What is the numerical value of the triple-point temperature of water on the Rankine scale?

Calculate the one temperature at which Fahrenheit and Kelvin thermometers agree with each other

Calculate the one temperature at which Fahrenheit and Celsius thermometers agree with each other.

Typical temperatures in the interior of the Earth and Sun are about 4000°C and 15 x 10⁶ °C, respectively. What percent error is made in each case if a person forgets to change °C to K?
