Which metal absorbs the greatest amount of heat energy
Fed [463]

Answer:

This question is incomplete but the completed question is in the attachment below. And the correct is b

Explanation:

Specific heat capacity can be defined as the amount of heat required to raise to raise 1 kg of a substance by 1 kelvin. Thus, this means that when the specific heat capacity of a substance is high, it takes more energy to increase the temperature of that substance. This also means that when different substances are subjected to the same amount of heat, the substance with the higher specific heat capacity will absorb less heat; for example at a beach, water has a very high specific heat capacity, thus when the sand in the beach is hot, the beach water is still relatively cold.

From the description above, <u>it can be seen that the metal with the least specific capacity will absorb the greatest amount of heat, thus the metal is lead</u> with the specific heat capacity of 0.129 J/(g. °C).

The quinine in tonic water shines a strange blue-white colour when lit with UV light. Explain what is happening here.
Alecsey [184]

Answer:

Here's what I get.

Explanation:

Quinine contains phosphors, substances that glow when they are hit with certain wavelengths of light.

The phosphors in quinine absorb UV light, which is invisible to our eyes.

Electrons in the phosphors absorb the UV energy and are excited to higher energy levels.

When the electrons drop back to lower energy levels, they emit some of this energy as a glowing blue visible light.
