Chemistry
1 answer:
cupoosta [38]2 years ago
5 0

Answer:

1. Temperature,  the average kinetic energy of particles, indicates how warm something is. Thermal energy, or the overall kinetic energy of the particles, indicates how a substance or material will transmit heat or chill something else.

2. A thermal expansion is a matter to change in volume in response to a change in temperature.

3. Heat is the form of energy that is transferred between systems or objects with different temperatures.

4. Air temperature near or over bodies of water is much different from that over land due to differences in the way water and land heat and cool. Properties that affect water temperature are transparency, ability to circulate, and specific heat.

5. Radiation is the transfer of heat energy through space by electromagnetic radiation.

6.  Radiation is natural and found everywhere, it comes from outer space, the air we breathe, and the earth we tread.

7. When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. The fluid above a hot surface expands, becomes less dense, and rises.

8. Convection currents in the Earth occur in the mantle

9. The fire's heat causes molecules in the pan to vibrate faster, making it hotter. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster.

10. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere.

Answer:

<em>I</em><em> </em><em>am</em><em> </em><em>giving</em><em> </em><em>u</em><em> </em><em>some</em><em> </em><em>explanation</em><em> </em><em>related</em><em> </em><em>this</em><em> </em><em>question</em><em> </em><em>pls</em><em> </em><em>see</em><em> </em><em>that</em><em> </em>

<em>it</em><em> </em><em>may</em><em> </em><em>help</em><em> </em><em>u</em>

Explanation:

The pH scale measures how acidic an object is. Objects that are not very acidic are called basic. The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic. Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0. A decrease in pH values from 5.0 to 4.0 means that the acidity is 10 times greater.

How pH is Measured

There are many high-tech devices that are used to measure pH in laboratories. One easy way that you can measure pH is with a strip of litmus paper. When you touch a strip of litmus paper to something, the paper changes color depending on whether the substance is acidic or basic. If the paper turns red, the substance is acidic, and if it turns blue, the substance is basic

The experimental group is the group that is left alone during the experiment
Paladinen [302]

Answer:

The given statement is false.

Explanation:

  • A common method of experimentation that is used to collect data on hypotheses of end up causing-effect is a contrast between two groups.
  • One community, the experimental group, is receiving medication for having any result. Some other group becomes left exposed, the control group, whether creating a different treatment.

As you move down a group of the periodic table how does the atomic radius of the atoms change​
lana [24]

Answer:

An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements. In general, the size of an atom will decrease as you move from left to the right of a certain period.

HELP ASAP!!!!!!
Sav [38]

1, 4, 1, 2, 1

Explanation:

We have the following chemical reaction:

MnO₂ + HCl → MnCl₂ + H₂O + Cl₂

To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.

So the balanced chemical equation is:

MnO₂ + 4 HCl → MnCl₂ + 2 H₂O + Cl₂
