Explanation:
As the water vapor touches the mirror the particles of the vapor loses energy and they move less then the process Condensation takes place in which the gas turns into water.
Answer: 1741289L
Explanation:
1 gallon = 3.78541 L
4.6×10^5 gallons = 4.6×10^5 x 3.78541 = 1741289L
Explanation:
According to the law of dilution,
The given data is as follows.
= 0.4782, 
= ?
= 0.025
, 
= 250 mL
Hence, we will calculate the value of as follows.
= 
= 13.07
Thus, we can conclude that we need 13.07 mL 0.4782 M sodium thiosulfate solution using pipette.
“Water” is the best thermal insulator.
Option: B
<u>Explanation</u>:
“Thermal insulators” are the materials which do not allow heat to transfer. “Water” is the substance which does not transfer heat. Hence, the “water” is the best “thermal insulator”. Water is the bad conductor of thermal heat. Water has “low thermal conductivity” than other substances, so this acts as an insulator as long as it is not traveled from one place to another. Heat is transferred when a “hot object collides” with “the cold objects”. The “thermal conductivity” of “water” is 0.6 W/m K.
