What makes an object hot or cold?
An object is hot or cold based on its temperature, which is a measure of the average kinetic energy of its particles. When particles move faster, they generate more heat, making the object feel hot. Conversely, when particles move slower, less heat is produced, causing the object to feel cold.
In which direction does air move: from hot to cold or from cold to hot?
Air moves from hot to cold.
Is water hot or cold?
Water can be either hot or cold depending on the temperature. Water at room temperature is considered neither hot nor cold.
How do you think the molecules move in hot and cold air?
In hot areas the molecules move quickly and in cold areas the molecules move slower.
What could be the temperature at cold objects compared to hot objects?
Cold objects generally have lower temperatures compared to hot objects. The temperature of a cold object is typically below room temperature (20-25 degrees Celsius), while the temperature of a hot object is usually above room temperature. The temperature difference between cold and hot objects can vary depending on the specific temperature of each object.
How fast do tiny water particles move?
it depends if its in a hot or cold temperature. hot = FAST cold = SLOW
Is vacuum cold?
"Cold" or "hot" are only defined when there are particles that move, so a temperature would not be defined for a perfect vacuum.

Is 65 c hot or cold?
It is hot, higher temperature is hot and lower is cold. Cold temperature is from 0c to about 10c.
Hot Approach and Cold approach in heat exchanger?
Hot Approach: It is difference in temperature of hot fluid inlet temperature and cold fluid outlet temperature Cold Approach: It is difference in temperature of Hot fluid outlet temperature and cold fluid inlet temperature. Mohsin
What are the differences in the way water molecules move in cold room temperature and in hot water?
In cold room temperature, water molecules move slower and are closer together due to lower kinetic energy. In hot water, molecules move faster and have more kinetic energy, causing them to spread out and move more freely. This difference in movement affects the density, viscosity, and behavior of water in each temperature condition.
In which direction does air move: from hot to cold or from cold to hot?
Air moves from hot to cold.
Is water hot or cold?
Water can be either hot or cold depending on the temperature. Water at room temperature is considered neither hot nor cold.
What temperature does it have to be for lizards hot or cold?
Cold
When the temperature is high is it cold or hot?
Hot
Wh is a temperature?
A temperature is how hot and how cold it is.
How do you think the molecules move in hot and cold air?
In hot areas the molecules move quickly and in cold areas the molecules move slower.
