What are the four liquids that can evaporate easily?
Water, ethanol, acetone, and gasoline are examples of liquids that evaporate easily due to their low boiling points.
Why do propane tanks stay cool when the burner is on?
Propane tanks stay cool when the burner is on because the propane inside the tank is converting from a liquid to a gas through a process called vaporization. This change in state requires heat energy from the surroundings, which causes the tank to feel cool.
Are short hydrocarbon molecules volatile?
Yes, short hydrocarbon molecules are typically volatile because they have low molecular weights and weaker intermolecular forces, allowing them to easily evaporate into the air at room temperature. Examples of short hydrocarbon molecules include methane, ethane, and propane.
Why hydrogendoes not evaporate easily alyhough it is non polar and lightast?
Because it is non polar
Why is propane used for heating and cooking?
Propane is commonly used for heating and cooking because it burns cleanly and efficiently, producing high heat levels. It is a convenient and cost-effective option for residential and commercial applications, as it can be stored in tanks and transported easily. Additionally, propane is a reliable energy source that is readily available in many areas.
