Answer and explanation:

A) An ideal fuel must:

- easy to transport and storage.

- have a high calorific value.

B) The <em>calorific value</em> for a fuel is the amount of heat - measured in Joules- which is produced during the complete combustion of the fuel. It is expressed in Joules per Kg of fuel (J/kg).

C) From the data:

mass of fuel = 2 kg

heat produced = 48,000 KJ

We calculate the calorific value by dividing the heat produced by the mass of fuel, as follows:

calorific value = heat produced/mass of fuel = (48,000 KJ)/(2 kg)= 24,000 kJ/kg

Since 1 KJ= 1000 J, we can express the calorific value in J/kg as follows:

24,000 kJ/kg x 1000 J/1 kJ = 2.4 x 10⁷ J/kg

Pressure cookers allow food to cook faster because the higher pressure inside the pressure cooker increases the boiling temperat
larisa86 [58]

Answer:

8.18K

Explanation:

This question is solved using the ideal gas equation:

PV=nRT

where,

P= pressure

V= volume

n= no. of moles

R= gas constant(8.314 J/K/mol)

T= temperature

Since in the question, volume of the container and amount of gas is not given,we'll assume a value for these variables and substitute it in our formula;

P= 3.4 atm

V= 1 litre (assumption)

n= 5 moles (assumption)

R= 8.314

T= ?

PV=nRT

3.4*1=5*8.314*T

T=3.4*1/0.08314*5

T= 8.18K
