Held constant, the pressure and volume of gas . its from boyle's law

Answer : When temperature is held constant, the pressure and volume of gas are inversely proportional.

Explanation :

Boyle's law : It is defined as at constant temperature and amount of gas remains unchanged, the pressure of the gas is inversely proportional to the volume of the gas.

Using ideal gas law equation :

where,

P = pressure of the gas

V = volume of the gas

n = number of moles of the gas

T = temperature of the gas

R = gas constant

At constant temperature and amount of gas remain unchanged, the ideal gas represented as,

where, k is constant.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
