Answer:

Their adaptations help them stay warm, hide, and defend themselves. In the harsh winter months, many animals have thick coats to keep them warm.

Small appendages that are close to the body stay warm and resist frostbite compared to having large ears or long tails. Thicker coats of either fur or hair grow in to act as an additional layer of insulation.
Hope this helps:)))

<span>you wanna use q=m*C*\Delta T\;

where Delta T=T_f-T_i for m, you wanna use the mass of the water not the octane because you're measuring the temp change of the water.</span>

If you place 2 moles of NaCL in a beaker and then add enough water to have a final volume of 0.5 liters, what is the molarity of
julia-pushkina [17]

Answer:

The molarity of the solution is 4M

Explanation:

Molarity is defined as the amount of moles of solute present in one liter of solution. So the molarity of any solution can be found by dividing the moles of solute between the volume in liters of the solution.

For this case we have:

M=\frac{2\:moles\:NaCl}{0.5\:L\:solution} =4M

Explain the changes in kinetic energy as a substance is heated to its melting point, and how these changes affect intermolecular
Drupady [299]

The more solid a substance is, the less kinetic energy there is. This is because there is not a lot of space for the atoms in the solid state to move. However, in the gaseous state, the atoms are far apart with plenty of space, this lets them create a lot more kinetic energy. Solids have a lot more intermolecular forces because the atoms are together. The IMF (intermolecular force) is what lets the atoms/molecules stick together. In the solid state, all the atoms are stuck together with little to no room in between. In the liquid state, it has a lot of IMF but is weaker then the IMF in the solid state. This is why you have so much resistance when you try to move through water. In the gaseous state, there is little to no IMF because the atoms are all so far apart. This makes it easier for everyone to move around.

To answer your question more directly: As the substance is heated to its melting point, there is an increase in kinetic energy, but decrease in intermolecular forces.

Of the groups given, which are the least chemically reactive?
AfilCa [17]

Answer:

Group 8A

Explanation:

This is because the elements in Group 8A is stable, what I mean is this elements have the maximum number of electrons in there last orbit so they dont need to form any compund with any other element in the periodic table.
