How does the density of propane compare to that of air?
The density of propane is higher than that of air. This means that propane is heavier than air and will sink when released.
What is the limits of flammability of propane?
Propane has a flammability range between 2.1% to 9.5% in air. This means that propane will ignite and burn when the concentration of propane in the air is between these two percentages. Outside of this range, the mixture will be either too lean or too rich to sustain combustion.
Is propane heavy compared to other gases?
Yes, propane is heavier than most common gases like air.
What in propane is flammable?
In propane, the chemical structure of the compound is what makes it flammable. Propane is made up of carbon and hydrogen atoms that can undergo combustion reactions with oxygen in the air to produce heat and light. This flammability is why propane is commonly used as a fuel source for heating and cooking.
Why is leak from propane dangerous?
A propane leak is dangerous because propane is flammable and can ignite easily, leading to fires or explosions. Additionally, propane leaks can displace oxygen in the air, creating a risk of suffocation in enclosed spaces. It is important to address propane leaks promptly and safely to prevent accidents.
Is there a difference in weight between hot air and cold air?
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.

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.
Does the weight of an air plain make a difference?
yes
Why does a hot air balloon have less mass at the end of a trip?
The propane used to burn is used up. Significantly reducing the weight
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.
What are facts about propane?
Propane pollutes the air around us. Propane is used as fuel and in chemical synthesis. Also propane is a nonrenewable gas.
What is the relationship between buoyant force and weight in air when submerged in water?
There's no relationship between the weight of an object in air and the buoyantforce on it when it's in water.The buoyant force is equal to the weight of the water the object displaces,which depends directly on its volume.Two objects that have identical weight in air will experience radically differentbuoyant forces in water if their volumes are different.
What makes an air balloon rise?
An air balloon rises due to the principle of buoyancy, which occurs when the hot air inside the balloon is lighter than the cooler air outside. This temperature difference creates a pressure difference, causing the balloon to float upwards.
