The pressure is decreased to 50 %.
The initial pressure is halved. Use Boyle's law that relates pressure & volume at a constant temperature. P1V1 = P2V2 In this case the V1(initial volume) is doubled so V2 = 2V1 P2 = P1V1/V2 = P1V1/2V1 P2 = (1/2)*P1
kelvin
Kelvin all measurements have to be recorded in kelvin instead of degrees Celsius because if you ever have to double the temperature and the temperature happens to be a negative number it will only become more negative and therefore not really exist so the all measurements of the average kinetic energy have to be in Kelvin.
Gay-Lussac's law relates the pressure of a gas to its temperature, under constant volume and amount of gas. It states that the pressure of a gas is directly proportional to its temperature in kelvin.
The standard temperature and pressure (STP) for chemical elements is usually defined as 0 degrees Celsius (273.15 Kelvin) and 1 atmosphere pressure. For lithium, this would be considered as STP for its properties and behaviors.
if kelvin temp is halved, the volume is halved if pressure is constant.
Because kelvin temperature has a simple relationship with volume, according to Charles's' law if the kelvin temperature becomes doubled at constant pressure the volume of the gas also becomes doubled, this relation is not with Celsius or Fahrenheit temperature.
The new pressure will be six times greater than the original pressure. This is because pressure is directly proportional to the number of molecules and temperature in Kelvin, according to the ideal gas law. Since both the number of molecules and temperature have increased, the pressure will triple for the increase in molecules and double for the increase in temperature, resulting in a total increase of 6 times.
According to Charles's Law, the volume of a gas is directly proportional to its Kelvin temperature when pressure is constant. Therefore, if the Kelvin temperature triples, the gas volume will also triple, so the gas volume will be 9 liters.
The initial pressure is halved. Use Boyle's law that relates pressure & volume at a constant temperature. P1V1 = P2V2 In this case the V1(initial volume) is doubled so V2 = 2V1 P2 = P1V1/V2 = P1V1/2V1 P2 = (1/2)*P1
The lowest kelvin temp is 0 K. All molecular movement stops.
373 kelvin 100 celsius kelvin is basically celsius + 273
A : 845.46 kPa
At stp or standard temperature and pressure, we have pressure = 100kPa and temperature=273.15 K
At STP(Standard Temperature and pressure), the temperature is zero degrees Celsius(273 Kelvin) and the pressure is 1 atmosphere. At RTP(Room temperature and pressure), the temperature is 25 degrees Celsius(298 Kelvin) and the pressure is 1 atmosphere.
They were looking for the word "temperature".
It isn't. Kelvin is a measurement of temperature on an absolute scale (0 Kelvin is the lowest possible temperature, 0 Celsius is about 273 Kelvin). The Earth's core temperature is about 5778 Kelvin around the same as the surface of the sun, so says Wikipedia
