Homework Statement
a. Consider an ideal gas being heated at constant volume, and let Cv be the gas's molar heat capacity at constant volume. If the gas's infinitesimal change in temperature is dT, find the infinitesimal change in internal energy dU of n moles of gas.
Express the...
Homework Statement
A rigid, perfectly insulated container has a membrane dividing its volume in half. One side contains a gas at an absolute temperature To and pressure Po, while the other half is completely empty. Suddenly a small hole develops in the membrane, allowing the gas to leak out...
Evaluate the line integral \int y^(2) dx + xy dy from A(1,0) to B(-1,4) with C: x = 1-t, y = t^(2), 0≤t≤2
I used:
Do I make the limits from 0 to 2? What do I do with the A(1,0) and B(-1,4)?
Please help? Thanks.
1. The problem
Use Differentials to approximate (24.5)^(1/2) + (9.5)^(1/2). Compare your answer to your calculator's answer.
Homework Equations
I used z = (x)^(1/2) + (y)^(1/2)
The Attempt at a Solution
What I used:
let z = (x)^(1/2) + (y)^(1/2)
x = 25
y = 10
dx = 0.5
dy = 0.5...
