One is for constant pressure, the other is for constant volume. These are not the same; for example, if the pressure is maintained constant, and the gas is heated, the volume changes.

Two equal masses of two different kinds of matter with two different specific heats is what?
sometimes have the same thermal energy
How did the scientists figure out what gasses are on the sun?
The gasses in the sun are very hot and therefore glow; the specific wavelengths of light that they emit are characteristic of specific elements.
What substance is used as the standard against which we meassure specific heats?
Water is used as the standard against which one measures specific heats. Water has a specific heat of 1 Btu/lb/deg F or 1 J/g/deg C.
Why is air heated from below?
Because sunlight is absorbed mostly by solid objects (not the gasses of the atmosphere), so the ground heats up, and warms the air adjacent to it.
What substance is used at the standard against which you measure specific heats?
water (H20)
Compared to water most metals have low specific heats.?
true
In what two places do convection currents form when the Sun heats Earth?
In what two places do convection currents form when the Sun heats Earth
When burning petrol in motor vehicles two gasses from which contributes to acid rains What are the two gasses?
Carbon and Oxygen. The gas is carbon-monoxide.
What are two natural gasses?
Oygen and Hydrogen
Do gases have specific heats?
Yes. Two specific heats are commonly defined: CV (constant volume specific heat and CP (constant pressure specific heat). For an ideal gas the relationship between the two can be calculated to be CP = CV + R The theoretical value of the specific heats for ideal gases can be estimated from the degrees of freedom of the gas - which in turn depends on it's structure. Monatomic gases really can only absorb energy by increasing their translational energy or boosting the electrons to higher orbitals. Diatomic gases add a degree of freedom for vibration and another for rotation (although diatomic molecules usually can store only and insignificant amount of energy in their rotations. Polyatomic molecules with more than two atoms have even greater degrees of freedom because they pick up vibrational modes for the additional molecular bonds and more rotational modes.
Does water heat up just as quickly as land heats up?
it heats up much faster, the specific heat value of water is very low, and the specific heat value of land is almost always higher than that of water.
What substance helps measure specific heats?
Specific Heat is the energy required to raise 1 g of any specific object by 1 degree Celsius.
