Due to "Temperature" difference heat is transferred from "one object" to "another object".

Explanation:

In general there are three ways for heat to be transferred: Conduction (heat is transferred by vibration of particles), Convection (heat is transferred by movement of particles) & Radiation (heat is transferred in Infrared waves). Heat is also called as thermal energy which acts as kinetic energy when energy is given to atoms, molecules, ions in solids, liquids and gases due to which movement takes place. As heat flows from higher temperature to lower temperature and heat content “Q” of an object depend upon its specific heat “c” and its mass “m”. For example when ice cube is added to room temperature water then transfer of heat energy will take place due to which ice melts in water and both of them reach to a common temperature which is also called as “Thermal Equilibrium” phase.

Which best explains the relationship between parent rock and soil composition?

irina1246 [14]

Soil is partially the result of the physical and chemical weathering of its parent rock. The minerals found in the soil were either in that parent rock, or they were formed from the weathering products of the parent rock.

During photosynthesis, plant cells use sunlight as an energy source; animal cells cannot do this. What substance do Animal cells

8090 [49]

Answer:

Chlorophyll

Explanation:

Photosynthesis is the process through which plant cells use carbon dioxide & water to create oxygen & energy rich organic compounds. They do so by converting sunlight ie light energy into chemical energy. This is possible due to presence of chlorophyll in them. Animals can't do so, as they dont have chlorophyll.

You’ve been waiting for the bus and your hands become cold. When you get onto the bus and sit down, you put your hands under you

snow_tiger [21]

Explanation:

The First Law of Thermodynamics states that energy cannot be created or destroyed in an isolated system. In other words, energy can be converted from one form into another, but it cannot be created nor destroyed.

Conduction is the transfer of energy from one molecule to another by direct contact. This transfer occurs when molecules hit against each other, which can take place in solids, liquids, and gases.

When you put your cold hands under your legs to warm your hands up, the heat energy from your legs is being transferred to your hands through conduction. However, since energy cannot be created, there is no extra heat energy that can instantaneously replace the heat created by your legs.

What has to be true of a substance for it to dissolve in water?

lord [1]

The polarity of a water molecule comes from the uneven distribution of electron density of hydrogen and oxygen atom. The oxygen in the water molecule is more electronegative than the hydrogen. Water has a partial positive charge near the hydrogen atom and a partial negative charge near the oxygen atom. The result of this electrostatic attraction results in the bond called hydrogen bond. Also, because of this bond, it has the ability to dissolve most of the solutes due to its polarity and bonding.

Answer: im thinking its gonna be d.C2H6 and also

the explanation is on the research i had did before i had answered this question so i really hope this help :)

Explanation:

Ar = van de waals forces or london forces

= van de waals forces or london forces

HCl=permanent dipole-dipole interactions

CO = permanent dipole-dipole interactions

HF = hydrogen bonding

= permanent dipole-dipole interactions
