Calculate the change in internal energy of the following system: A balloon is cooled by removing 0.659 kJ of heat. It shrinks on
bixtya [17]
<h2>Answer:</h2>

-310J

<h2>Explanation:</h2>

The change in internal energy (ΔE) of a system is the sum of the heat (Q) and work (W) done on or by the system. i.e

ΔE = Q + W       ----------------------(i)

If heat is released by the system, Q is negative. Else it is positive.

If work is done on the system, W is positive. Else it is negative.

<em>In this case, the system is the balloon and;</em>

Q = -0.659kJ = -695J    [Q is negative because heat is removed from the system(balloon)]

W = +385J  [W is positive because work is done on the system (balloon)]

<em>Substitute these values into equation (i) as follows;</em>

ΔE = -695 + 385

ΔE = -310J

Therefore, the change in internal energy is -310J

<em>PS: The negative value indicates that the system(balloon) has lost energy to its surrounding, thereby making the process exothermic.</em>

What is the difference between Weight and Mass?<br>Please give a fair amount of detail!
Sidana [21]
The <em>mass</em> of an object is a measure of how much stuff it's made of.  So it's
a property of the object, like the object's length or color.  It doesn't depend on
where the object is located right now, or on what else is around it..

The <em>weight</em> of an object is the measure of the gravitational force between it
and something else.  The strength of the force depends on the size of both
masses, and also on how far apart they are.  So the weight does depend on
where the object is located right now, and on what else is around it.

I think that sums it up fairly well.

answer questions1) The south pole of the steel magnet will be brought closer to the iron nail head. Which pole will be at the po
Anvisha [2.4K]
Answer:

North pole

Explanation:

According to the law of magnetism:

<em>Unlike poles attract while like poles repel</em>

Since the south pole of the steel is brought near the nail, and the nail is meant to attract the steel magnet, the nail domain realigns itself to produce a pole opposite to the pole of the steel magnet brought near it.

Since the North pole is the opposite of the south pole, the North pole will be at the pointed end of the nail so that it can attract the steel magnet.
