what is change in internal energy if 30j of heat are released from a system that does 50j of work on its surroundings
slamgirl [31]

Answer:

-80 J

Explanation:

The first law of thermodynamics states that:

\Delta U = Q - W

where

\Delta U is the change in internal energy of the system

Q is the heat absorbed by the system

W is the work done by the system

In this problem, we have:

Q = -30 J is the heat released by the system (negative because the system releases it)

W = +50 J is the work done by the system on the surrounding (positive since it is done by the system)

Therefore, the change in internal energy is

\Delta U = -30 J - (+50 J) = -80 J

At 0.0 degrees Celsius, a wire cable is 410.0000 meters in length. When the temperature increased to 30.0 degrees Celsius, the w
zzz [600]

Answer: The coefficient of expansion for the wire 0.000028 (^oC)^{-1}.

Explanation:

Original length of the wire = L= 410.0000 m

Initial temperature =T_1=0.0^oC

Final Temperature = T_2=30.0^oC

Increase in Length of the wire = \Delta L=0.3444 m

\frac{\Delta L}{L}=\alpha _{L}\times \Delta T=\alpha _{L}\times (T_2-T_1)

\alpha _L=\frac{\Delta L}{L\times (T_2-T_1)}=\frac{0.3444 m}{410.0000 m\times (30.0^oC-0.0^oC)}

\alpha _L=0.000028 (^oC)^{-1}

The coefficient of expansion for the wire 0.000028 (^oC)^{-1}.

A 5-kg brick sliding on an ice covered pond has a kinetic energy of 16 Joules. a box of identical mass but half the speed is sli
ludmilkaskok [199]
It would have 8 joules because if the box is going half the speed with the same mass the you would just divide the joules in half
