Which of the methods of heat transfer generally involve mass movements?
Convection is the method of heat transfer that generally involves mass movements. It occurs when a fluid (liquid or gas) moves due to density differences caused by changes in temperature. This movement helps to transfer heat from one place to another.
What type of heat transfer occurs in only liquid and gases?
Convection is the type of heat transfer that occurs in only liquids and gases. It involves the transfer of heat through the movement of the fluid molecules due to differences in their density and temperature.
Can a sensible heat and latent heat transfers be read with a thermometer?
yes
A transfer of heat within a liquid or gas that involves warm particles moving in currents is?
Convection is the transfer of heat within a liquid or gas that involves warm particles moving in currents. It occurs due to the difference in density between the hot and cold regions of the fluid, causing the fluid to circulate and transfer heat energy.
What is transfer of energy by changes in density is?
Transfer of energy by changes in density is known as convection. This occurs when a fluid, such as air or water, is heated and becomes less dense, causing it to rise and transfer heat from one place to another. Conversely, when the fluid cools and becomes denser, it sinks, completing a cycle of energy transfer.
What is the name for temperature changes which involves no heat transfer?
Adiabatic

What are the 3 main types of heat transfer and how are each of the different?
Radiation - electromagnetic, thus no material need be in contact with the radiating object. Conduction : heat conducted by direct contact. Convection : heat is 'conducted' to a transfer material (fluid) which then caries it away by gravity (changes in density).

What is the process of heat transfer in gases and liquids?
Heat transfer in gases and liquids occurs primarily through conduction, convection, and radiation. Conduction involves the transfer of heat through direct physical contact between molecules. Convection involves the transfer of heat through the movement of fluids. Radiation involves the transfer of heat through electromagnetic waves.
Which type of heat transfer creates currents and cannot occur in solids?
Convection heat transfer creates currents and cannot occur in solids. Convection involves the transfer of heat through the movement of fluids (liquids or gases) due to differences in temperature and density. This process helps distribute heat in fluids, such as air and water.
What is it called the movement of material due to differences in density?
The movement of material due to differences in density is called convection. This process involves the transfer of heat through the movement of fluids such as air or water.
How does the density of the molecules affect heat transfer?
The density of molecules affects heat transfer by determining how closely packed the molecules are. Higher density means more molecules per unit volume, leading to more efficient heat conduction. Lower density results in slower heat transfer due to fewer molecules available for heat energy to be transferred through.
What does Heat transfer by convection requires to transfer heat?
Heat transfer by convection requires a fluid (liquid or gas) to transfer heat. The fluid circulates due to temperature differences, carrying heat from one place to another. Convection is more efficient in fluids compared to solids because molecules in fluids can easily move and transfer heat through their motion.
