At high pressure the boiling point is higher.
The boiling temperature of a liquid increases as the gas pressure a the liquid's surface increases.
As altitude increases, atmospheric pressure decreases.
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
Atmospheric density is a function of altitude, temperature, and pressure. As altitude increases, density decreases due to the lower pressure and temperature in the upper atmosphere. Conversely, density increases at lower altitudes where pressure and temperature are higher.
when temperature of air increases it becomes less dense and expands rising up which causes the pressure to drop
Temperature and altitude are two qualities that affect atmospheric pressure. As temperature increases, air molecules move faster and create higher pressure. At higher altitudes, there are fewer air molecules above, leading to lower pressure.
Atmospheric pressure will decrease as altitude increases.
Water's boiling point decreases with increases in elevation due to the reduction in atmospheric pressure at higher altitudes. Boiling occurs when the vapor pressure of the liquid equals the surrounding atmospheric pressure. As altitude increases, the lower atmospheric pressure means that water can reach its boiling point at a lower temperature. This is why, for example, water boils at a temperature lower than 100°C in mountainous regions.
Temperature increases as pressure increases.
The boiling point of isopropyl alcohol (isopropanol) is approximately 82.6°C at standard atmospheric pressure (1 atm). When the external pressure is increased, the boiling point of isopropyl alcohol also increases. This is because a higher pressure requires the liquid to reach a higher temperature for its vapor pressure to equal the external pressure, allowing it to boil. Thus, under increased pressure conditions, isopropyl alcohol would boil at a temperature above 82.6°C.
as pressure increases, temperature increases
As the atmospheric pressure changes, the force pushing on the surface of the liquid changes. Therefore,the height of the liquid in the tube increases as the atmospheric pressure increases.
