Answer: Nitrogen normally exists as two-atom molecules in the form of a gas at room temperature.
Explanation:
Explanation:
The kinetic energy of a gas molecule is given by :
It means, whenever the temperature of gas is increased, its kinetic energy will increase and the space between the particles gets increase. So, the space in which particles can collide with each other increases i.e. its volume gets high.
Hence, the correct option is (A). "higher temperature more kinetic energy → more space between particles – higher volume".
We can directly solve
this problem using the wavelength formula which is:
wavelength = speed of
light / frequency
We know from the given
that 99.30 FM = 99.30 MHz, therefore:
wavelength =
(2.99*10^8 m/s) / (99.30*10^6 Hz) <span>
<span>wavelength = 3.011 meters</span></span>
Answer:
The student needs to increase the length of the heating element
Explanation:
Increasing the length of the heating elements helps to increase the surface area of the heating elements which allows for more water to come in contact with the heating element
