39.95)

1) 5203 2) 5302
3) 2305. 4)3025

Answer 1

It is tungsten not argon

Ok

Answer 2

Answer:

The specific heat of  argon at constant pressure is 0.5203 kJ/kg K.

Explanation:

Given that,

Specific heat of argon = 0.3122 kJ/kg/K

Molecular weight of argon = 39.95

We need to calculate the specific heat of  argon at constant pressure

Using formula of specific heat

$c_{p}-c_{v}=\dfrac{R}{M}$

$c_{p}=\dfrac{R}{M}+c_{v}$

Where, $c_{p}$ = specific heat at constant pressure

$c_{v}$ = specific heat at constant volume

Put the value into the formula

$c_{v}=\dfrac{8.314}{39.95}+0.3122$

$c_{v}=0.5203\ kJ/kg K$

Hence, The specific heat of  argon at constant pressure is 0.5203 kJ/kg K.
