Question

I need help with this. (THE 3 QUESTIONS PLEASE) 100 points.

Answer 1

Step-by-step explanation:

2.When the distance an object travels is directly proportional to time, it is said to travel with Constant Speed.

Speed= time/distance travelled

3.

At constant temperature, ΔT=0

∴ΔU=nC

v

ΔT

∴ΔU=q+w=0

q=−w

When work done is zero, w=0

∴ΔU=q+w

∴ΔU=q

In gaseous system, w=PΔV

∴ΔU=q+w

∴ΔU=q+PΔV

When work is done by the system, w is negative.

∴ΔU=q−w
