What substances catches fire in the presence of moisture in the air at room temperature?
lithium
Why does a room with a gas fire need to be ventilated?
First warm/hot air is lighter than cool/cold air. As the fire in the fireplace consumes oxygen from the surrounding air, it is also heating this air. This heated air then rises, and as it rises cooler air is drawn in from the surrounding room. As long as the air in the fireplace is warmer than the air in the room, this process will continue..
Do Gas Fires dry the air?
Yes, gas fires can contribute to dry indoor air because they release combustion byproducts like water vapor, which can increase a room's humidity level. However, if a gas fire is not properly ventilated, it can also deplete the moisture in the air. It is important to balance the use of a gas fire with proper ventilation to maintain a comfortable level of humidity in the room.
What does fire and air make?
fire and air makes a fire tornado, also known as the fire devil or fire whirl.
How can water and air stay in the same room?
Water and air can stay in the same room because they are both forms of matter that can coexist together. The water molecules remain in a liquid state due to their intermolecular forces, while the air molecules move freely in the space around them. There is no specific barrier preventing water and air from occupying the same space.
How do a chimney and an open fire help to ventilate a room?
A chimney helps to ventilate a room by drawing up warm air and smoke from the fire and expelling it outside. This creates a natural airflow that brings fresh air into the room. The open fire also helps by consuming oxygen and creating a pressure differential that encourages fresh air to enter the room.
How does a coal fire help to ventilate a room as well as heat it?
Some of the heat from the fire goes up the flue as hot air. This creates a draught, pulling fresh air into the room.
Where does the oxygen come from when the log fire is burning?
From the air in the room where the fireplace is.
How fast to air molecules move at room temperature?
Air molecules at room temperature (~20°C) typically move at speeds around 500 m/s. This movement contributes to air pressure and properties such as diffusion and convection.
What causes fire in the Philippines?
it is caused by the air. when i walk in the room. i am so hot. i am too hot and that makes. FIRE!
Does cold air go up or down in a room?
Cold air tends to sink and move downwards in a room, while warm air rises and moves upwards.
Does cold air travel up or down in a room?
Cold air tends to sink and move downwards in a room, while warm air rises and moves upwards.
What substances catches fire in the presence of moisture in the air at room temperature?
lithium
What removes air out a room during a fire?
the reaction that makes fire is fueled by oxygen therefore as the fire burns the oxygen molecules are consumed
What two ways does a fireplace heat a room?
By convection (air warmed by the fire circulates through the room) and radiation (infrared energy given off by the fire is transmitted directly, warming objects in line-of-sight of the fire).
Would a balloon filled with minus 2 degrees Celsius air move to room temperature of 8 degrees Celsius Explain?
A balloon filled with -2 degrees Celsius air will move to a room to a temperature of 8 degrees Celsius because of the collision of the air particles.
Why does a room with a gas fire need to be ventilated?
