Temperature: Videos & Practice Problems

The absolute zero is the temperature at which all particles move/vibrate at the least speed possible. Absolute temperature scales include the Kelvin scale and the Rankine scale. Determine the boiling point of water on the Rankine scale. 

What is the value of a temperature that is the same in both Fahrenheit and Kelvin thermometers? 

A temperature appears the same in both the Fahrenheit and Celcius thermometers. What is its value?

In the cores of Jupiter and a white dwarf star, the typical temperatures are about 3.0×10⁴°C and 5.0×10⁶°C, respectively. If someone forgets to change degrees Celsius to Kelvin, what percent error is made in each case?

The core temperature of an industrial furnace is measured at about 1500 °C for optimal performance monitoring. Convert this temperature to Fahrenheit scale.

In a mercury-in-steel thermometer, the mercury column measures 15.25 cm at -20.0°C and extends to 35.45 cm at 80.0°C. Calculate the temperature when the length of the mercury column is observed to be 28.85 cm.

Helium gas is filled in a cylinder to a pressure of 150 atm at a temperature of 35 °C. The cylinder is then placed in a cooler environment, and after some time, the pressure gauge reads 140 atm. Assuming the volume of the cylinder remains constant and that no gas escapes or is added, what is the temperature of the cooler environment in °C?

The temperature at sea level is about 25 degrees Celsius. At the highest point on Earth, Mount Everest, the temperature is around -19 degrees Celsius. Convert both of these temperatures into Kelvin.

A scuba diver's air tank contains gas that is at a pressure of 150 atm and is at a temperature of 25.0°C. In order to drop the pressure of the gas to 100 atm, what temperature should the gas be cooled to? Assume that the tank's volume and the quantity of gas will remain constant.

A scuba diver fills her diving tank with air at the surface of the water where the pressure of air is 1.0 atm. She then dives to a depth where the pressure is 0.85 atm. Assuming that the temperature of the water does not affect the air temperature in her tank, by what percentage has the volume of the air in her tank increased compared to the condition when it was filled with air above the surface of the water?

A research station located at sea level, where the temperature of the air surrounding the station is 25.0°C and the pressure of the air is 1.0 atm, releases a weather balloon. The balloon ascends to 5000 m, where the temperature of the air is -10.0°C and the pressure of the air is 0.54 atm. Compare what the balloon's volume was at 5000 m to what its volume was at sea level.

You’re following a recipe that requires you to bake a cake at 350°F. To understand this temperature in Celsius, what is the equivalent value?

The extreme body temperatures recorded in mammals show a wide range. A camel in the scorching desert can reach a body temperature of 113°F, while a hibernating groundhog can have a body temperature as low as 50°F. Convert these temperatures to the Celsius scale.

A laboratory sample has a temperature of 42°C. Convert this temperature to the Kelvin scale.

A helium spherical balloon is filled at sea level with a volume of 2.00 m³ at a temperature of 20.0°C. The balloon rises to an altitude where the pressure is 0.60 atm and the temperature is -10.0°C. What will be the new radius of the balloon at this altitude?

A scientist measures the temperature of a chemical reaction to be 25 degrees Celsius. What is this temperature in Fahrenheit?

A hot air balloon is floating in the air with some riders. The initial temperature of the air inside the balloon is at 20°C. Afterward, the temperature of the air inside the balloon is increased to 30°C. Determine by what percentage the buoyant force on the balloon changes, if the temperature of the surrounding air and the pressure of the air inside the balloon remains unchanged.
