What else can I help you with?
When a fixed sample of gas increases in volume what happens to the pressure and temperature?
The frequency of collisions is reduced
What happens to the particles of matter when a liquid changes to a gas-?
The particles are no longer fixed by the forces keeping it a liquid
If a fixed sample of gas increases in temperature it must also do what?
If a fixed volume of gas increases in temperature, it must increase in volume. If the gas is in a closed system, the pressure inside that system increases instead. When the gas increases in volume, it also decreases in pressure, often rising above colder, more dense gas if possible.
What liquid evaporates at 120 degrees Celsius?
Any substance which is liquid at that temperature. Liquids evaporate at any temperature. If you mean boiling, which happens at a fixed temperature at fixed pressure, then nitric acid fits.
Does a pure substance always boil at a fixed temperature?
Yes, a pure substance boils at a fixed temperature under a specific pressure. This boiling point is characteristic of the substance and remains constant as long as the pressure is maintained. However, if impurities are present or if the pressure changes, the boiling point can vary.
When a fixed sample of gas increases in volume what happens to the pressure and temperature?

Why is body temperature not a good fixed temperature for establishing a temperature scale?
Not everyone has the same body temperature and it changes with throughout the day
If a fixed sample of a gas increases in temperature at a constant pressure its volume does what?
If a fixed sample of gas increases in temperature at constant pressure, its volume will also increase. This is because as the temperature increases, the particles in the gas gain more kinetic energy and move faster, causing them to collide with the container walls more frequently and with greater force, thus occupying a larger volume.
When a fixed sample of gas increases in volume?
When a fixed sample of gas increases in volume, its pressure decreases because the gas particles have more space to move around, resulting in fewer collisions with the container walls. The temperature of the gas typically remains constant.

Do liquids have fixed temperature but no fixed shape?
Yes
What is lower fixed point?
upper fixed point is a temperature of stem from water boiling and standards atmospheric pressure lower fixed point is the temperature of pure melting ice.
Does a pure substance always boil at a fixed temperature?
Yes, a pure substance boils at a fixed temperature under a specific pressure. This boiling point is characteristic of the substance and remains constant as long as the pressure is maintained. However, if impurities are present or if the pressure changes, the boiling point can vary.
Compared to the particles in a hardened lava sample the particles in a liquid lava sample?
The particles in a hardened lava sample will be solidified and compacted, while the particles in a liquid lava sample will be molten and in a flowing state. The hardened lava particles will have a crystalline structure, whereas the liquid lava particles will lack a fixed arrangement due to their high temperature.
Does water has a fixed volume?
No, it does not. The volume of water changes according with it's temperature. Water, unlike other substances, it has a minimum volume at 4 degrees Celsius.
