When matter and energy change forms within a closed system?

2 answers:

Matter becomes energy. Law of thermodynamics states that matter can't be created or destroyed, but can transfer to another form. If it was closed in with the form of energy, it would be transferred to the form of energy.

Answer:

The total amount of both matter and energy remains the same

Explanation:

The matter is defined as anything that has some weight and it occupies some volume.

On the other hand, energy is defined as the capacity/ability to do work.

According to the law of conservation, it says that energy can neither be created nor destroyed, but it transforms from one kind to another.

Also according to Einstein's mass-energy equation, it says that matter that is comprised of certain energy is equal to the product of their mass and square of its light speed.

Thus, in a closed system, both matter and energy can change its forms but their total amount remains the same.

Monica [59]

Loss on the transaction is $37,000

As per given data

Cost of Cages = $206,790

Accumulated depreciation = $186,111

Selling Price = $18,611.10

Sale price of Asset is compared with the net book value of that asset to calculate the gain or loss arising from the sale of asset.

Net book value is the net value of the cost of asset and the accumulated depreciation of that asset.

Net Book Value = Cost of Cages - Accumulated depreciation

Net Book Value = $225,000 - $170,000 = $55,000

Selling Price = $18,000

Loss on Sale of asset = $55,000 - 18,000 = $37,000

Therefore,

Loss on the transaction is $37,000

A 0.1 kg block of brass is cooled until it releases 56.4 J of heat. If the temperature of the block was 5 K initially, what is i

Zolol [24]

Answer:

3.5 K

Explanation:

When a sample of a substance releases heat energy, its temperature decreases according to the equation:

$Q=mC(T_f-T_i)$

where

Q is the heat energy released

m is the mass of the substance

C is the specific heat capacity

$T_i$ is the initial temperature

$T_f$ is the final temperature

For the block of brass in this problem, we have:

m = 0.1 kg is the mass

Q = -56.4 J is the heat energy released (negative since it is released)

C = 380 J/kg K is the specific heat capacity of brass

$T_i=5 K$ is the initial temperature

Solving for $T_f$ , we find the final temperature:

$T_f=T_i + \frac{Q}{mC}=5+\frac{-56.4}{(0.1)(380)}=3.5 K$
