3 0

Answer:

Some chemical indicators perceived while a piece of paper is burning are:

Production of an Odor: there is a smell of burnt paper

Change in Temperature:  combustion is a highly exothermic reaction , so the temperature increase

Change in Color: paper changes to ashes as the burning process occurs

Water can exist in three states of matter. Imagine examining the changes of state from solid to liquid to gas by adding to ice.
loris [4]

<u>Answer:</u>

<em>We know water can exist in all three states be it solid or liquid or gas the only difference between the three states is the temperature at which they exist. </em>

<u>Explanation:</u>

When the temperature moves towards colder region the state of water changes to solid while when the temperature moves to water region the state of water changes to gas.

This little experiment can be done with the help of ice at room temperature. The more ice is applied to water it will turn to ice but removal of eyes in room temperature. And will make it turn to water and complete removal of eyes with application of heat would make it into vapour.

Answer: Rubber source, temperature, thinkness, thread design, driving pattenrs, weather, etc.

Explanation: There are many variables. Here are a few I would include in a tire lifetime study:

1. Type of rubber, including source

2. Thickness of tire

3. Design of tire thread

4. Life as a function of average speed and road surface

5. Expected outside temperature and wet conditions

6. Driving conditions of speed and both acceleration and deceleration parameters (e.g., tire life when slamming on the brakes or accelerating quickly)

Which does not affect chemical equilibrium
Amanda [17]
An inert gas will not react with either the reactants or the products, so it will have no effect on the product/reactant ratio, and therefore, it will have no effect on equilibrium.
