In hot temperatures, liquids with lower boiling points evaporate first, such as alcohol. In cold temperatures, liquids with higher boiling points, like water, are slower to evaporate. At room temperature, liquids like acetone evaporate quickly, while oils and glycerin evaporate more slowly.
As the liquid evaporates at room temperature, the system will experience a decrease in the amount of liquid present and an increase in the amount of vapor in the container. This will result in a change in the pressure and temperature within the system as the liquid continues to evaporate.
a gas it becomes a gas at -42 C room temperature is 20 C
Gasoline is a liquid. It is a liquid because the gasoline u pour
Whether or not the density changes if some of the liquid evaporates between the time the liquid is delivered to the beaker and the time it is measured depends on the liquid. For almost all liquids, the answer is no because there was not enough time. Water will have a density of approximately 1 and if a small amount evaporates, it will still have the same density. If you had the beaker at 100C and the room at 0C and waited until the water was 4C, it would make a difference. If the water was at 40C and the room was at 30C, it would almost make no difference. A very few substances would undergo tremendous cooling. That would bring a corresponding increase in density.
Patrol (also known as petroleum ether) evaporates at room temperature because it has a low boiling point. The molecules in patrol have weak intermolecular forces, which allows them to easily escape from the liquid phase and enter the gas phase at room temperature. This rapid evaporation is why patrol is highly volatile and can be dangerous if not handled properly.
As the liquid evaporates at room temperature, the system will experience a decrease in the amount of liquid present and an increase in the amount of vapor in the container. This will result in a change in the pressure and temperature within the system as the liquid continues to evaporate.
Liquid nitrogen does not freeze instantly; instead, it evaporates rapidly at room temperature. When it comes into contact with objects, such as food or skin, the extreme cold temperature of liquid nitrogen can cause rapid freezing of the water content in those objects, giving the appearance of instantaneous freezing.
The difference at room temperature is not significant.

Bromine is a halogen which can be a gas or liquid depending on the temperature. At room temperature bromine is a liquid metal.
When the liquid is exposed to extreme heats, it evaporates, forming a gas. This is because of the particles shrinking and being able to move around more freely. If it is exposed to cold temperatures, the particles enlarge, so that there is not much room for movement, causing a solid object.
Liquid bromine has weak intermolecular forces, which allow individual molecules to easily overcome these forces and escape into the gas phase at room temperature. This is why liquid bromine evaporates and changes into a gas.
Gasoline is a liquid. It is a liquid because the gasoline u pour
Acetone evaporates as a gas because its molecules have enough kinetic energy to escape from the liquid phase and enter the gas phase. Since acetone has a relatively low boiling point, it evaporates easily at room temperature, even in an open bottle or container.
Clearly, this depends on the temperature of the room. In most countries, cooking oil will be liquid at room temperature. However in very cold countries, cooking oil will be solid at room temperature.
Bromine is a dull, dark red-brown liquid at room temperature. It has a slightly shiny appearance when in its liquid state, but it quickly evaporates into a reddish-brown gas, which is not shiny.
Isopropyl alcohol typically evaporates at room temperature within a few minutes to an hour, depending on the surface area and volume of the liquid.
