A flask contains 0.83molof neon gas at a temperature of 35°C. The pressure gauge indicates 0.37atm inside the flask. What is the
blsea [12.9K]

Answer:

V = 56.72 L

Explanation:

Given data:

Number of mole of neon gas = 0.83 mol

Temperature = 35°C

Pressure = 0.37 atm

Volume of gas = ?

Solution;

Temperature = 35°C  (35+273 =308K)

Formula:

PV = nRT

R = general gas constant = 0.0821 atm.L/mol.K

Now we will put the values in formula.

V = nRT/P

V = 0.83 mol ×0.0821 atm.L/mol.K ×308K / 0.37 atm

V = 20.99 L/  0.37

V = 56.72 L

Aluminum has a specific heat of 897 j/kg c. methanol has a specific heat of 2450 j/kg c.
Vikki [24]

Answer:

\sf \: correct  \: answer  \: would \:  be \:  methanol!

Explanation:

<em>Specific Heat:</em><em> </em>The specific Heat of any material is the heat absorbed or evolved by the material to raise or fall it's temperature by 1°C per unit mass of the material.

The heat absorbed or evolved (Q) is directly proportional to the mass of substance(m) and rise or fall of temp(∆T)

The general formula for specific heat is,

\sf \: \: \: \: \: s = \frac{Q}{m\Delta T}

Where

  • s is specific heat,
  • Q is the Heat absorbed or evolved
  • m is mass of substance
  • & ∆T is change is temperature

<em>Now coming to your question,</em>

<em>The specific heat of Aluminium is 897 J/kg °C</em>

<em>The specific heat of Aluminium is 897 J/kg °C& specific heat of methanol is 2450 J/kg ° C</em>

The definition states that, <u>if the specific heat would be more, more amount of heat will be required for per unit change in temperature.</u>

The specific heat of Aluminium is 897 J/kg °C which means for one kilogram aluminium, 897 Joule energy is required to change it's temperature by 1°C & Similarly for one kilogram methanol 2450 joule energy is required.

Hence, the correct answer would be methanol!
