Because the electrons in it are moving about. This is similar to what happens when you run about, you become 'hot'.
The room won't immediately become warmer; however, when the curtains are closed, less heat will escape through the windows.
The spoon will absorb heat from the hot soup through conduction, causing it to become warmer. This transfer of heat occurs because there is a temperature difference between the hot soup and the spoon, leading to thermal energy flowing from the soup to the spoon until they reach thermal equilibrium.
Warmer
The surroundings become warmer when propane reacts with oxygen as it undergoes combustion, releasing heat energy as a byproduct of the reaction.
I would think in warmer Air....
as air become warmer velocity of sound increases
move faster.
move faster.
Convection is the process that transfers heat through a flowing material, such as air or water. As the material flows, warmer parts rise and cooler parts sink, creating a continuous circulation that helps distribute heat. This process is commonly observed in fluids and gases.
The warm water currents in the ocean make the atmosphere warmer hence the climate of those regions become warmer.
Heat always flows from warmer objects to cooler objects, unless you have a device (like a heat pump) to prevent this. The natural tendency is for two or more objects at different temperatures to eventually all have the same temperature and this is accomplished by heat flowing from the warmer objects to the cooler objects.
Air mass conduction is the transfer of heat through direct contact between the air and a surface. This process occurs when warmer air comes into contact with a cooler surface, causing the air to lose heat and become cooler. Conversely, when cooler air touches a warmer surface, it gains heat and becomes warmer.
