When a solid is placed in a container and heat is applied, a phase change occurs. Watch the video and identify which of the foll

owing statements are correct. Check all that apply. View Available Hint(s) Check all that apply. The temperature increases while all of a liquid is converted to a gas. When a solid is converted to a liquid, heat is absorbed. The average kinetic energy of the system changes while all of a solid is converted to a liquid. Temperature remains constant while all of a solid is converted to a liquid. When heat is applied to a solid, the molecular motion decreases as the temperature increases.

Kinetic energy

<h2> Further Explanation </h2>

Energy is something that is very inherent in every activity of life. Simply stated, energy can be interpreted as the ability of an object to make an effort. An object is said to have energy when it is able to produce power that can work.

Kinetic, Potential, and Mechanical Energy is a type of energy that is almost present in every part of human life. Its existence cannot be eliminated because of its enormous benefits for the development of human technology, especially those relating to the movement of objects, the position of objects, or a combination of the two.

Kinetic energy is the energy of motion, the energy possessed by objects or objects due to their motion. Kinetic energy comes from the Greek word kinetics which means to move. So, you certainly know that every object that moves then that object has kinetic energy.

The kinetic energy of an object is defined as the effort needed to move an object with a certain mass from rest to a certain speed.

The kinetic energy of an object is equal to the amount of effort required to express its speed and rotation, starting from the others.

Kinetic energy is influenced by the mass and velocity of an object as it moves. The mass is symbolized by the letter m, while the speed is symbolized by the letter v. The amount of energy is directly proportional to the amount of mass and magnitude of the speed of an object as it moves.

Objects with large mass and velocity must have large kinetic energy when moving. And vice versa, objects whose mass and velocity are small, their kinetic energy is also small.

In table below, there are descriptions of an experiment on samples of three different chemical compounds. Decide whether the com
likoan [24]

Answer:

Compound 1 is molecular

Compound 2 is ionic

Compound 3 can't really be decided

Explanation:

A molecular substance does not conduct electricity, has very low melting and boiling points and is held together by very weak intermolecular forces.

An ionic substance conducts electricity in solution or in molten state but never in the pure solid state, has a high melting and boiling point and has a dull appearance most times.

Compounds 1 shows the properties of molecular substances hence it are designated as such.

On the other hand, compound 2 shows the properties of an ionic substance and is also designated as such.

We can't really decide on compound 3 because it shows some properties of ionic substances and some properties of molecular substances.

What is advantage of using single fixed pulley although it doesnot multiply force?​
luda_lava [24]

A single fixed pulley is used to lift load by changing the direction of the lifting force. Even though a single fixed pulley has no mechanical gain in that, the effort applied is greater than the load, it is preferred in use since you do not have to pull or push the pulley up and down.

Noise Pollution: An Invisible Threat to Humans and animals.
soldi70 [24.7K]

Answer:

Explanation:

Noise pollution occurs when we have a house which is more than 65 decibels. The effects of noise pollution include physical effects which can be respiratory agitation, headaches, high blood pressure, etc.

Another effect is the psychological effect such as depression, anxiety, fatigue etc. Stress can also lead to sleep disorders and lack of concentration.

The ways to reduce noise pollution are:

1. Using awareness campaign: People should be told about the harmful effects of noise. This will be vital in reducing noise.

2. Government control: Government can play their role by telling those who doesn't adhere to laid out rules regarding noise to pay a fine. Anyone found wanting should pay a fine.
