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.

If you increase the temperature of an object does it affect the volume?
Yes, it does affect the volume. The relationship between them can be explained by the equation pV=nRT (pressure x volume = number of moles of gas x molar gas constant x temperature). Therefore, there is a direct proportionality between temperature and volume. If the temperature doubles, so does the volume.
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.
What woul happen to the volume of the 100L weather balloon if its temperature increases from 25 C TO 125 C while the external pressure remain constant?
The universal gas equation is PV = nRT (Pressure x Volume = Number of moles x Universal Gas Constant x Temperature in Kelvin/Rankin). So - if Pressure is constant, the number of moles is constant, but the temperature increases from 25C (298 K) to 125C (398K) - a 34% increase, a similar 34% increase in volume will occur.
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?
For a fixed mass of gas, the gas will become compressed by pressure and its volume will decrease. This is why pressurized gas containers explode when breached: the container breach eliminates the barrier between the gas compressed by the container and the outside air; the pressurized gas immediately increases the volume it occupies in the explosive decompression until its density equals the density of the regular atmosphere.
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, it does affect the volume. The relationship between them can be explained by the equation pV=nRT (pressure x volume = number of moles of gas x molar gas constant x temperature). Therefore, there is a direct proportionality between temperature and volume. If the temperature doubles, so does the volume.
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.
