What else can I help you with?
When the volume of gas decreases the pressure increases is called?
This is known as Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume when temperature is kept constant. This means that as the volume decreases, the pressure increases, and vice versa.
What is it called when The volume of a gas increases as temperature increases?
Charles's Law states that (Volume)/(Temperature) is constant, assuming constant pressure and moles of gas. This means that (V1)/(T1) = (V2)/(T2). So if the volume of the gas increases, V2 is bigger than V1; to keep the ratio constant, T2 must also increase, which represents an increase in temperature.
What is it called when an animal maintains a constant internal temperature even when it is cold outside?
It is called homeostasis (internal environment maintained at a constant level) or thermostasis (internal heat maintained at a constant temperature). The overall name for the processes by which temperature is controlled is thermoregulation.
If pressure is applied to a confined volume of gas the temperature of that gas will increase. Will that in effect negate Boyle's law?
By "confined" it is assumed that no heat exchange is allowed. This is sometimes called an "adiabatic" change. P V = R T still applies, but since the temperature changes, P x V is no longer constant. The relation for adiabatic changes is often expressed as P x V^gamma = constant, where gamma is is a constant and the ^ sign means "raised to the power". Using algebra these 2 equations can be combined to eliminate one of the variables P or V, to give relationships between V and T, or between P and T. "Negate" is too strong a word here. Boyle's law refers to constant temperature, so it cannot be used when the temperature changes. When you compress a gas at constant temperature, heat passes out. If it is thermally isolated the heat is retained and shows up as a rise in temperature.
The measure of the total amount of solid material dissolved in seawater is called?
salinity
The temperature at which the vapor pressure of a liquid is equal to the external pressure is?
The temperature at which the vapor pressure of a liquid equals the external pressure is called the boiling point. This is when the liquid changes into vapor at a constant temperature.
If the temperature of a fixed amount of gas is increased at a constant pressure what will happen to a volume?
Volume will increase. Think of it this way. If you heat a gas, it gets hotter. When a gas gets hotter, the atoms/molecules are "more active" and the pressure and/or the volume will go up. If your experiment with heating this gas sample must have a constant pressure, then volume will have to increase to give all those "more active" atoms/molecules more play room to prevent the pressure from going up.
What is it called when the volume of a gas increases and the pressure decreases?
Charles' Law says that as pressure on a gas decreases, its volume increases. Charles' Law is an example of an inverse relationship.t It is not Charle's law It is Boyle's law Charles law states at constant volume, pressure is proportional to kelvin temperature And at constant pressure volume is proportional to kelvin temperature But Boyle's law states that at constant temperature pressure is inversely related to volume
Vapor pressure is measured when a liquid and its vapor are?
in a state of dynamic equilibrium at a constant temperature. At this point, the rate of vaporization equals the rate of condensation, resulting in a constant pressure above the liquid known as the vapor pressure.
Pressure and volume changes at a constant temperature can be calculated using?
Boyle's Law, which states that pressure and volume are inversely proportional at a constant temperature, expressed as PV = constant. Mathematically, this can be written as P1V1 = P2V2, where P represents pressure and V represents volume at different points in the process.
As the temperature of a gas increases the volume of the gas must also increase to maintain constant pressure.?
That is correct. it's called Charles's law. it shows the connection between a gases temperature and its volume. in order to maintain constant pressure you must increase the volume of the container holding the gas if you increase the temperature of the gas.
What is the temperature at which a liquid and gaseous phases are in equilibrium?
The temperature at which a liquid and gas are in equilibrium is called the boiling point. At this temperature, the vapor pressure of the liquid equals the atmospheric pressure, allowing the liquid to change into gas and vice versa at a constant rate.
What is the relationship between volume temperature and pressure that is useful for designing things with fixed-volume pistons?
You can use the ideal gas law: PV=RTn, where: P is the pressure V is the volume R is the proportionality constant, the so-called "gas constant" T is the absolute temperature n is the number of moles
The constant pressure in the walls of the arteries is called?
Diastolic pressure
What is a factor held constant?
In science, as in real life sometimes several 'factors' effect the outcome of an experiment. In order to make the problem easier to study one or more of these is 'held constant' or not allowed to change in order to see the effect of the other variables. EX. Gas volume can be effected by both pressure and temperature. In order to understand the effect of pressure, Boyle kept the temperature constant. He then changed the pressure to see what happened to the volume of a gas. This gave him what is now called Boyle's Law: The volume of a gas varies inversely as the pressure when the temperature is held constant.

What happens to the pressure if the temperature in K is doubled?
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
