Answer:

Physical Properties of Carbon:

Carbon is a unique element. It occurs in many forms. Some examples of the pure form of carbon are coal and soot.

It is soft and dull grey or black in colour.

One of the most important compounds of carbon is the charcoal, which is formed when carbon is heated in the absence in of air.

It occurs in a number of allotropic forms. Allotropes are nothing but forms of an element with varying physical as well as chemical properties.

The density of the different forms of carbon depends upon the origin of these elements. You will find some forms of carbon which are pure and some forms which are not pure like coal which is the mixture of both carbon and hydrogen.

Chemical Properties of Carbon

Carbon compounds generally show 4 reactions, they are

Combustion reaction

Oxidation reaction,

Addition reactions

Substitution reaction.

As we all know that carbon in all forms needs oxygen, heat, and light and forms carbon dioxide. When it is burned in air to give carbon dioxide, it is called as combustion.

Let us get the concept of this using some examples when it is burnt in the air: When methane CH4 is burnt in the presence of oxygen it gives us carbon dioxide, heat, and light.

What is the kinetic energy of a 1130 kg truck that is moving with a velocity of 40 m/s?
Makovka662 [10]

Answer:

The answer is 904,000.

Kinetic energy=1/2mv^2.

1/2×1130×40^2.

1/2×1808000=904,000Joules.

The perimeter of a rectangle can be found using the equation P = 2L + 2W, where P is the perimeter, L is the length, and W is th
sweet [91]

Answer:

The perimeter of the rectangle is 60 units.

Explanation:

The perimeter of a rectangle is given by the equation P = 2L + 2W. With W = 12 units and L = 18 units, substituting the values in the equation above:

P = 2(18 units) + 2(12 units)

P = 36 units + 24 units

P = 60 units

What is thermal energy?A hot potato at 100 ºF is placed in a bowl of soup at 80 ºF. The surrounding room is at 65ºF. Which corre
jasenka [17]

Answer:

1. Thermal Energy is the internal energy that is produced from the temperature of a heated substance/object.

2. From the potato to the soup and from the soup to the surrounding room

Explanation:

1. When an object or substance is heated it causes a rise in temperature which makes the atoms and molecules within the object move/vibrate faster and collide with each other. This kinetic energy energy comes from the temperature of the object being heated and is the thermal energy.

2. The atoms present in a hot object have higher kinetic energy when compared to a colder object and usually flow towards the colder object. This is why it is possible for the hot potato whose temperature is higher than the bowl of soup to flow towards the soup and from the soup to the surrounding room.
