<u>Answer:</u>
<em>1. A NaCl solution with a concentration of 50g/100mL of water at 40°C:</em> The NaCl solution with a given concentration is saturated at this temperature .As the temperature increases the solution will more dissolves.
<em>2. A sugar solution with a concentration of 200g/100mL of water at 40°C: </em>The sugar solution with a given concentration is saturated at this temperature. As the temperature increases the solution will more dissolves.
<em>3. A sugar solution with a concentration of 240g/100mL of water at 40°C:</em> The sugar solution with a given concentration is saturated at given temperature.

Answer:
False.
Explanation:
Removing the radiator cap will harm you. If the engine is hot and you open the radiator cap then it will cause the liquid boil, pushing the coolant out of the radiator and spraying around the liquid which can harm the person who is opening that cap. So you should aware of the risk and be prepared to avoid danger.
The answer is Conduction: the process of heat is directly transmitted through a substance when there is a difference in temperature.
Answer:
The energy of each photon in the light beam is 
.
Explanation:
Given that,
Index of refraction of glass =1.55
Index of refraction of material =1.30
Wavelength = 115 nm
We need to calculate the energy of each photon in the light beam
Using formula of energy
Where, h = Planck constant
=wavelength
c = speed of light
Put the value into formula
Hence, The energy of each photon in the light beam is .
