How Are Temperature And Kinetic Energy Related? Flashcards
What is the temperature of the Boomerang Nebula?
The Boomerang Nebula has a temperature of -272°C.
It is located 5,000 light years from Earth.
How is energy transferred between water at different temperatures?
Energy is transferred from water at a higher temperature to water at a lower temperature.
The water at the higher temperature contains more energy.
What is energy transfer in terms of temperature?
Energy, in the form of heat, is transferred from objects at higher temperatures to those at lower temperatures.
What happens when warmer water samples are mixed with colder water samples?
Energy is transferred from the warmer water molecules to the colder water molecules until all molecules have roughly similar amounts of energy.
What does the temperature of a gas measure?
The temperature of any gas is a measure of the kinetic energy of its molecules.
What happens to the kinetic energy of gas molecules when temperature increases?
When the temperature of gas molecules is increased, their kinetic energy increases in a straight line, indicating that kinetic energy is directly proportional to temperature.
What is the relationship between kinetic energy and temperature?
Kinetic energy and temperature have a linear relationship above absolute zero.
What is the freezing point of water on the Celsius scale?
Zero degrees Celsius is the temperature at which water freezes.
What is absolute zero in the Kelvin scale?
Zero Kelvin is equal to negative 273 degrees Celsius and is called absolute zero.
What occurs at absolute zero?
At absolute zero, all molecular movement would stop, although it is thought to be impossible to achieve.
What is heat in terms of thermal energy?
Heat is the transfer of thermal energy.
What happens to energy transferred to a substance?
When energy is transferred to a substance, it may be converted to kinetic energy.
How is the kinetic energy of molecules related to temperature?
The kinetic energy of the molecules in a substance is directly proportional to their temperature.
What does the temperature of molecules indicate?
The temperature of the molecules is a measure of their kinetic energy.
