V1/T1 = V2/T2
Temperature must be converted to absolute temperature by adding 273. O oC = 273 K
Substituting:
5.0 / 278 = V2 / 283
V2 = 5.0 x 283 / 278
V2 = 5.09 L
= 5.1 L (2 significant figures)

646/3=273x
x= (215 + 1/3)/273 = 8x10(-1) liters, or 0.8 liters.

Is the vapor pressure of a liquid a linear function of temperature?
No, the vapor pressure of a liquid is not a linear function of temperature. It follows the Clausius-Clapeyron equation, which is an exponential relationship between vapor pressure and temperature. As temperature increases, the vapor pressure of a liquid typically increases exponentially.
If you increase the temperature of an object does it affect the volume?
Yes, typically as the temperature of an object increases, its volume also tends to increase. This relationship is known as thermal expansion, where materials expand when heated and contract when cooled.
What is an Arrhenius equation?
An Arrhenius equation is an equation which approximates the dependence of the rate of any chemical reaction on the temperature.
How are pressure volume and temperature of gases related?
The temperature, pressure, and volume of gases can be related by the ideal gas equation. PV = nRT where P is pressure, V is volume, n is moles, R is that ideal gas constant, and T is the temperature in Kelvin.
What is the statement defining the relationship between the pressure and volume of a gas at constant temperature?
I'd use a graph showing an exponential decrease: as pressure increases, volume decreases.
What law relates pressure and temperature at a constant volume as temperature increases pressure increases?
You can use the Ideal Gas Equation: pV=nRT or p1V1/T1 = p2V2/T2
At which temperature in water does sound travel the fastest?
Sound travels faster as temperature increases, so there is no limit. There is an equation to determine the speed of sound at a given temperature.
What happens when air gets compressed?
Air warms up when it gets compressed. The equation is PV = NrT where P is pressure, V is volume, N is a number of molecules, r is the gas constant and T is the temperature.
When a pressure on a gas increases will the volume increase or decrease?
When pressure on a gas increases, the volume of the gas will decrease. This is known as Boyle's Law, which states that at constant temperature, the volume of a gas is inversely proportional to its pressure.
What must be done if a transaction increases the left side of the accounting equation?
Correct the transaction so that the double entry also increases the right hand side of the accounting equation so that the equation (always) balances.
How would you describe varies directly and show it in an equation?
when x increases y increases.. y=kx
If you increase the temperature of an object does it affect the volume?
Yes, typically as the temperature of an object increases, its volume also tends to increase. This relationship is known as thermal expansion, where materials expand when heated and contract when cooled.
Application of differential equation in temperature?
Newton's equation of cooling is a differential equation. If K is the temperature of a body at time t, then dK/dt = -r*(K - Kamb) where Kamb is the temperature of the surrounding, and r is a positive constant.
Compressed springs are what kind of energy?
The potential energy of a spring is defined by this equation: U=.5kx2 U= potential energy (in joules) k= the spring constant x= the displacement of the spring from equilibrium. (the amount that the spring is stretched or compressed) This equation tells us that as a spring is compressed by a distance x, the potential energy increases proportionately to x2
What is an Arrhenius equation?
An Arrhenius equation is an equation which approximates the dependence of the rate of any chemical reaction on the temperature.
When the temperature is constant gas volume will decrease as the pressure decreases is that true?
If I remember correctly it is a little more complicated than that. The general equation PV=nRT for an ideal gas is elementary knowledge. The fact is that when you increase temperature many things can happen. It depends on how you treat your system. In general if you increase temperature in an open system the pressure will remain fairly constant, but the volume will increase. If it is a closed system in which the volume is not allowed to expand the pressure will increase with increased temperature. You also have to remember chemical properties also such as phase changes. Hope that rambling mess helps lol.
Will the ideal gas equation only give correct values if the temperature is expressed in degrees Celsius?
In the ideal gas equation the temperature is in kelvins.
