What does 20 Celsius mean?
Ah, 20 degrees Celsius is a comfortable temperature that many people find pleasant. It's not too hot or too cold, just right for enjoying a nice day outside or cozying up indoors. Remember, it's always good to dress appropriately for the weather and stay hydrated to feel your best.
Can water be made to boil at 95 or 105C?
Yes. The temperature can be reduced by lowering the "atmospheric" pressure: for example by going up a mountain. The boiling point can be raised by increasing the pressure - in a pressure cooker, for example, or by dissolving a solute such as salt.
If the air temperature is 30 degrees Celsius and the relative humidity is 60 percent will the dew point be reached if the temperature drops to 25 degrees Celsius?
If the air temperature drops to 25 degrees Celsius and the relative humidity remains at 60 percent, the dew point will not be reached. The dew point is the temperature at which air becomes saturated and condensation forms. In this case, the temperature would have to be lowered further for the dew point to be reached.
What is boiling point of sodium chloride solution?
Well, that is dependent upon several factors. 1. air pressure: lower pressure will result in a lower boiling point. 2. concentration of the solution: if you were to add 1 milligram of salt to 1 liter of water, there would be hardly any difference in the boiling point of the solution. If instead you added 58.5 grams of salt, there would be a significant, not to mention calculable, difference in the boiling point. In general, the more salt you dissolve, the high the boiling point will be raised.
which function is performed by earth’s atmosphere?
Earth's temperature is raised and moderated by trapping in heat.
Rigid container holds hydrogen gas at a pressure of 3.0 atmospheres and a temperature of 2 degrees Celsius Whatwill bethe pressure if the temperature is raised to 10 degrees Celsius?
Rigid container holds hydrogen gas at a pressure of 3.0 atmospheres and a temperature of 2 degrees Celsius. The pressure if the temperature is raised to 10 degrees Celsius will be 15 atmospheres based on the law of pressure for gas.
What relationship exits between gas pressure and temperature?
Gas pressure and temperature have a direct relationship. If the pressure is raised, then the temperature will also raise, and vice versa.
Is it possible for water on earth to be a liquid at temperatures higher than 100 degrees celsius?
Of course,if enough pressure is applied temperature of liquid water can be raised upto 374 degrees celcius without converting to vapour.
What happens to the volume of gas when its temperature is raised and its pressure is kept constant?
When the temperature of a gas is raised while keeping its pressure constant, the volume of the gas will also increase. This is described by Charles's Law, which states that the volume of a gas is directly proportional to its temperature when pressure is held constant.
A quantity of a gas has an absolute pressure of 400 KPa and absolute temperature of 110 Kelvin when the temperature of the gas is raised to 235 kelvin what is the new pressure of the gas?
A : 845.46 kPa
What shall you do to increase evaporation rate of water?
You add more heat to it (water can go no hotter than 100 degrees no matter how hard you heat it). that isn't true. if you use a pressure cooker you can heat water hotter because you have raised the pressure the temp can therefor be raised. Yes, the critical temperature of water(the max temperature that water can exist as a liquid, even with unlimited pressure exerted) is around 373.95degrees Celsius. To answer your question, you can add heat, decrease vapour pressure, or increase surface area.
What will happen to a real gas when the temperature is lowered and the pressure is raised?
When the temperature is lowered and the pressure is raised on a real gas, the molecules will move more slowly and be forced to be closer together. This can lead to the gas condensing into a liquid or solid, depending on how low the temperature goes and how high the pressure is increased.
Is the vapor pressure of a liquid a linear function of temperature?
If the temperature of the liquid is raised, more molecules escape to the vapor until equilibrium is once again established. The vapor pressure of a liquid, therefore, increases with increasing temperature.
A quantity of a gas has an absolute pressure of 400kPa and an absolute temperature of 110 degrees kelvinwhen the temperature of the gas is raised to 235degrees kelvin what is the pressure of the gas?
Using the combined gas law (P1/T1 = P2/T2), we can calculate the pressure of the gas at the new temperature. Plugging in the values, we get P2 = (P1 * T2) / T1 = (400 kPa * 235 K) / 110 K = 853 kPa. Therefore, the pressure of the gas is 853 kPa when the temperature is raised to 235 degrees Kelvin.
A quanitity of gas has a volume of 0.20 cubic meters and an absolute temperature of 333 degrees kelvin when the temperature of the gasis raised to 533 degrees kelvin whats is the new volume of the gas?
D. 0.3198 m3
What is the change in a state if matter from a gas to a liquid?
It is called condensation, and usually occurs as temperature is lowered, or pressure is raised.
Why is a liquid cooled system is pressurised?
Basically what happens when a liquid is pressurized is that the boiling point of that liquid is increased to say 138 degrees, so this would be the boiling point instead of 100 degrees. So for every 1 bar of pressure the temperature is raised say by 30 degrees, and the aid of antifreeze effects this boiling point as well.
