Distinguish between temperature and thermal energy
MissTica

Answer:

<u>The difference between temperature and thermal energy is that temperature measures the average kinetic speed of molecules and thermal energy is the total kinetic energy of all particles in a given substance.</u> Convection occurs when energy is transferred while the mass of a substance moves. The temperature is measured in Celsius, Kelvin, and Fahrenheit. The temperature does not depend on the quantity of the substance – it is related to the average kinetic energy of the particles. The thermal energy depends on the quantity of the substance – it is related to the total kinetic energy of the particles.

Calculate the number of moles of a gas if it occupies a volume of 4dm at 10atm and _200°c.
Rina8888 [55]
 The number  of moles of a gas if it occupy a volume of 4dm  at 10 atm and - 200 c   is 6.67  moles

  calculation
by use of ideal gas equation
that is PV =nRT
where  P(pressure) =  10 atm
           V( volume) =  4dm^3 = 4L
            n(number of moles) =?
             R(gas constant) = 0.0821 L.atm/mol.K
              T = -200  +273 =  73 K

make n the  formula  of  the subject  n = PV/RT

n is therefore =  (10 atm x 4l)/(0.0821 L.atm/mol.K  x 73 K)  =  6.67 moles
