Yes, there is a difference in weight between hot air and cold air. Hot air is lighter than cold air because the molecules in hot air are more energetic and spread out, decreasing the overall density of the air. This difference in weight is a factor in phenomena such as convection currents.

How can we measure the upthrust of an object?

The upthrust of an object can be measured by determining the difference between the object's weight in air and its weight when immersed in a fluid. This difference in weight is equal to the upthrust force acting on the object. It can be calculated using the formula: Upthrust = Weight in air - Weight in fluid.


Why does cold air sink on one side of the air while warm air is blown on the other side of the room?

Cold air is denser than warm air, so it tends to sink. When cold air infiltrates a room, it displaces the warmer air, forcing it to rise and creating a temperature difference between the two sides. This temperature difference can cause air circulation patterns where cold air sinks on one side while warm air rises on the other.


What force causes a difference in weight in air and water?

The force of buoyancy is responsible for the difference in weight between an object in air and water. In water, the upward force of buoyancy counteracts some of the object's weight, making it feel lighter. This is due to the water pushing against the object with an upward force equal to the weight of the water displaced by the object.


What is the relationship between buoyant force and weight in air when submerged in water?

When submerged in water, an object experiences an upward buoyant force equal to the weight of the water displaced by the object. This buoyant force reduces the effective weight of the object in water compared to its weight in air. The difference between the object's weight in air and its effective weight in water is equal to the buoyant force acting on the object.


When you open a door does hot air go out or coldair come in?

When you open a door, hot air goes out and cold air comes in due to the difference in temperature between the inside and outside of the space. This happens because warm air has a tendency to rise and escape, while cold air tends to move in to replace it.

What is the difference in density between warm and cold air?

Warm air is less dense than cold air because the molecules in warm air have more energy and are more spread out, resulting in lower density. Cold air is denser because the molecules are closer together and moving slower.

What is the difference between heat and air?

heat is hot, air is cold Heat and air differ in every respect; heat is a form of energy that is transferred by a difference in temperature, and air is a mixture of gases.


How Cold Should the Air Be from your Air Conditioner?

What creates the air pressure difference between the equator and the poles?

The air pressure difference between the equator and the poles is primarily caused by the temperature difference. Warm air at the equator rises, creating a low-pressure area, while cold air at the poles sinks, creating a high-pressure area. This temperature difference drives atmospheric circulation, resulting in the pressure gradient between the two regions.


How does a cold front form and what effect does a cold front have on weather?

A cold front forms when colder air advances toward warm air. The cold air wedges under the warm air like a plow. As the war air is lifted, it cools and water vapor condenses, forming clouds. When the temperature difference between the cold and warm air is large, thunderstorms and even tornadoes may form.


Why does cold air sink on one side of the air while warm air is blown on the other side of the room?

Cold air is denser than warm air, so it tends to sink. When cold air infiltrates a room, it displaces the warmer air, forcing it to rise and creating a temperature difference between the two sides. This temperature difference can cause air circulation patterns where cold air sinks on one side while warm air rises on the other.

Does the weight of an air plain make a difference?

yes


Why is there a difference between the weight of an object in the air and it's weight in water?

Because of buoyancy ; something that acts in the opposite direction to the force of gravity to make the object feel lighter.
