Answer:
Specific heat at constant pressure is = 1.005 kJ/kg.K
Specific heat at constant volume is = 0.718 kJ/kg.K
Explanation:
given data
temperature T1 = 50°C
temperature T2 = 80°C
solution
we know energy require to heat the air is express as
for constant pressure and volume
Q = m × c × ΔT ........................1
here m is mass of the gas and c is specific heat of the gas and Δ
T is change in temperature of the gas
here both Mass and temperature difference is equal and energy required is dependent on specific heat of air.
and here at constant pressure Specific heat is greater than the specific heat at constant volume,
so the amount of heat required to raise the temperature of one unit mass by one degree at constant pressure is
Specific heat at constant pressure is = 1.005 kJ/kg.K
and
Specific heat at constant volume is = 0.718 kJ/kg.K
Answer: I have more time to think about the wonderful things in life that we don't always appreciate.
Explanation:
3. Law: Every action has a reaction equal in magnitude and opposite in direction.
Explanation:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Answer:
The mutual inductance is 
Explanation:
From the question we are told that
The number of turns per unit length is 
The radius is 
The number of turns of the solenoid is 
Generally the mutual inductance of the system is mathematically represented as
Where A is the cross-sectional area of the system which is mathematically represented as
substituting values
also 
is the permeability of free space with the value 
So
