How is it possible that heat is transferring from the water in the tank to the water in the bag, even though the water in the tank doesn’t feel hot?
Answer:
animals unlike us adapt faster to heat/cool weather or water
Explanation: Let's use fish as an example because that's the main water pet, so when you get a new fish and you have to put it in the water for about let's say 15 minutes. It's so it can adapt to the water. Water for us needs to be hot enough for us to actually feel the heat so therefore animals can adapt not only faster to heat but to cool air/water a lot faster than we can. I don't know if this helps or makes sense but it's what I know and have seen :P
Fredrick has two samples of pure water - sample X and sample Y. Sample X has a volume of 1 L and sample Y has a volume of 10 L. How do the boiling points of these two samples compare?
Group of answer choices
Sample X will boil at a lower temperature because it has less volume.
Sample Y will boil at a lower temperature because it has more volume.
Which ever sample receives heat first will have a lower boiling point.
Sample X and Y will boil at the same temperature.
Answer:
D. Sample X and Y will boil at the same temperature
Explanation:
The boiling point of a liquid is the temperature at which the vapor pressure equals the atmospheric pressure.
The boiling implies a phase change of water from liquid to vapor. This requires an input of energy in the form of heat. Since Y has a greater volume than X, Y will require a higher heat input. However, the boiling temperature will remain unchanged.

If the reactant contains one chlorine Molecule, Do you know how many Chlorine Atoms will be in the Product? Include Conversations Of matter in your explanation.
Answer:
2 chlorine atoms.
Explanation:
H₂ + Cl₂ → 2HCl
The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction.
If 2 molecules of Hydrogen and 2 molecules of Chlorine is present in the reactants, the same no. of atoms should also be present in the product.
∴ the no. of chlorine atoms in the product is 2.

A student filled a shallow pan of with water and wanted to investigate waves. The student used a dropper to drip water onto the surface and then made observations. Figure one shows the student view looking down on the pan.
Which of the following statements about the waves in the pan is true?
A.Waves transfer matter
B.Waves transfer energy
C.Waves transfer matter and energy
D.Waves transfer neither matter nor energy
Answer:
B
Explanation:
Waves does not transfer matter. Waves does not add any matter but it does add energy becuase of the movment.
The water waves are mechanical waves and they transfer both matter ad energy. Therefore, option C is correct.
What are mechanical waves ?Mechanical waves are those waves which can pass through a medium only. Hence, they are not like an electromagnetic wave which passes through vacuum too.
There are two types of mechanical waves namely, transverse waves and longitudinal waves are those in which the oscillation of particles is in the direction of the wave propagation.
In transverse waves, the oscillation is in perpendicular to the direction of propagation. Water waves are transverse waves. They can transfer both energy and matter. Hence, option C is correct.
