Describe the relationship between the forces of attraction and the kinetic energy of particles in a solid, a liquid and a gas

Physics
1 answer:
mel-nik [20]3 years ago
5 0

Answer:

Described below

Explanation:

1) Solids: In solids, the strong attractive forces between the particles ensure that the particles are packed tightly enough and this means little or no movement between each other. However, when they experience vibration which has relationship with the kinetic energy between them

2) Liquids; In liquids due to the lesser forces of attraction between the particles, it means they tend to glide over each another but however, toward the bottom of the container they will settle. This means that the attractive forces between the liquid particles are barely strong enough to hold onto a specific volume. However, they are not strong enough to keep the molecules from sliding over one other.

3) Gases; In gases, there is almost no existing attractive force in most cases and as a result we can say the kinetic energy of the gas molecules is always greater than the attractive force between them and they are therefore far apart from each other and also move independent of each other.

Your washer has power of 450 watts, and your dryer has a power of 3000
qaws [65]

Answer:

See explanations below

Explanation:

Power = Workdone/Time

Power of washer = 450watts

Time used to clean the clothes = 1hour = 3600secs

Energy used to clean a load of clothes in 1 hour of

washing = 450/3600

Energy used to clean a load of clothes in 1 hour of

washing = 0.125Joules

For drying;

Energy = 3000/1.5*3600

Energy = 3000/5400

Energy = 0.556Joules

Hence the energy in washing id 0.556Joules

Find the voltage change when: a. An electric field does 12 J of work on a 0.0001-C charge. b. The same electric field does 24 J
kondaur [170]

Explanation:

Given that,

(a) Work done by the electric field is 12 J on a 0.0001 C of charge. The electric potential is defined as the work done per unit charged particles. It is given by :

V=\dfrac{W}{q}

V=\dfrac{12}{0.0001}

V=12\times 10^4\ Volt

(b) Similarly, same electric field does 24 J of work on a 0.0002-C charge. The electric potential difference is given by :

V=\dfrac{W}{q}

V=\dfrac{24}{0.0002}

V=12\times 10^4\ Volt

Therefore, this is the required solution.

Why do things become hot or cold?<br> Relate to Thermal Energy and The Law of Conservation of Energy
Mekhanik [1.2K]

<u>Answer:</u>

Things become hot and cold because of the transfer of energy.

<u>Explanation:</u>

The energy possessed by an object or system is called thermal energy and heat is the flow of this energy. While the law of conversation of energy states that energy is not destroyed or created, it just transfers from one object to another.  

When a hot object is placed in normal conditions, it transfers heat to the environment until both are at the same temperature and heat transfers from the environment to the cold objects placed in normal conditions.
