If nonsalt water is placed in a closed system (for example an automotive cooling system) then for every pound of pressure the system can handle (ex. radiator cap) the boiling point of water (normally being 212f) is raised by 3 degrees. Thus, if said system can handle only 1 pound pressure before the water boils the temperature of the water when it boils should be 215F. Or so I understand.
Increasing pressure will increase the boiling point of butane. This is because higher pressure forces the butane molecules closer together, making it harder for them to escape into the vapor phase, thus requiring a higher temperature to boil.
Lowering the pressure, the boiling point is lowered; the classic example is water at high altitude.

Which has a lower boiling point butane or water?
Butane has a lower boiling point than water. Butane boils at -1°C (30.2°F) while water boils at 100°C (212°F) at standard atmospheric pressure.
The freezing point and the boiling point of water can be altered by a variety of techniques Which of the following has little or no effect on the boiling point of water?
Pressure changes have little effect on the boiling point of water. The boiling point of water changes depending on the pressure, but the effect is minimal compared to other factors like adding solutes or using a catalyst.
Why does a butane lighter work poorly in cold weather?
Butane lighters can work poorly in cold weather because the cold temperature affects the vaporization of butane, making it harder to ignite the flame. Lower temperatures can also decrease the pressure inside the lighter, making it difficult to generate the necessary spark for ignition.
In a pressure cooker a lid is screwed tightly onto a pot so that the air pressure in the pot is increased What effect if any will this have on the boiling point of water in the pot?
Increasing the air pressure in the pot will raise the boiling point of water. This is because with increased pressure, water molecules require more energy to overcome the higher pressure and vaporize, leading to a higher boiling point than at normal atmospheric pressure.
Which of these alkanes methane ethane propane and butane expect to have the highest boiling point?
Butane would be expected to have the highest boiling point among methane, ethane, propane, and butane. This is because as the number of carbon atoms in the alkane chain increases, so does the strength of the intermolecular forces (London dispersion forces), leading to higher boiling points.
What is the alkane with a boiling point of 0?
Methane is the alkane with a boiling point of 0°C. It is a gas at room temperature and pressure.
Which has a lower boiling point butane or water?
Butane has a lower boiling point than water. Butane boils at -1°C (30.2°F) while water boils at 100°C (212°F) at standard atmospheric pressure.
What is the effect of pressure on boiling?
Lowering the pressure the boiling point is also lower.
The freezing point and the boiling point of water can be altered by a variety of techniques Which of the following has little or no effect on the boiling point of water?
Pressure changes have little effect on the boiling point of water. The boiling point of water changes depending on the pressure, but the effect is minimal compared to other factors like adding solutes or using a catalyst.
What is the effect of decreased pressure on boiling point and freezing point of water?
Decreased pressure lowers the boiling point of water because it reduces the pressure exerted on the liquid, allowing the water molecules to escape into the vapor phase more easily. However, decreased pressure has a less significant effect on the freezing point of water compared to the boiling point, as freezing point is more influenced by the presence of impurities in the water.
Why does a butane lighter work poorly in cold weather?
Butane lighters can work poorly in cold weather because the cold temperature affects the vaporization of butane, making it harder to ignite the flame. Lower temperatures can also decrease the pressure inside the lighter, making it difficult to generate the necessary spark for ignition.
Does melting point and boiling point of liquid changes from altitude to altitude?
The boiling point depends on altitude (pressure). The effect on the melting point is not significant.
How does altitude effect boiling points?
The higher the pressure, the higher the boiling point. Boiling occurs when the atmospheric pressure equals the vapor pressure. So, at higher altitudes where the atmospheric pressure is lower, the vapor pressure is also lower which in turn creates a lower boiling point which causes foods to have to cook longer.
As you go to higher elevations above sea level the boiling point of water?
as you go higher above sea level, pressure decreases. Due to the decrease in pressure, the temperature needed for water to boil is less than it is than it would be at sea level. Thus, it would take less heat energy for the bonds to break and become a gas than it would in an environment with more pressure.
What is the freezing point of butane?
n-butane : Melting point −138.4 °C (135.4 K), boiling at −0.5 °C (272.6 K)iso-butane (methylpropane): Melting point -159.6 °C, (114 K) , boiling at -11.7 °C, (261 K)
When is boiling point?
Boiling point is when the liquids pressure equals the pressure of the atmosphere.
