Answer:
"How does the volume of a gas kept at constant pressure change as its temperature is increased?"
Explanation:
One possible question can be:
"How does the volume of a gas kept at constant pressure change as its temperature is increased?"
The answer to this question is contained in Charle's law, which states that for a gas at constant pressure, the volume of the gas is proportional to its absolute temperature:
Or also written as
By looking at this equation, we can find immediately the answer to our question: as the (absolute) temperature of the gas increases, the volume increases as well, by the same proportion.
Answer:
a) yield strength
b) modulus of elasticity
strain calculation
strain for offset yield point
=0.0046-0.002 = 0.0026
now, modulus of elasticity
= 184615.28 MPa = 184.615 GPa
c) tensile strength
d) percentage elongation
e) percentage of area reduction
