Answer:
4
Explanation:
1 is correct
Liquids have no definite shape as they take up the shape of the container. Thus, we can say a liquid has no shape of its own but rather has the shape of the container in which it is filled.
2 is correct
When the atmospheric temperature is increased, it also will increase the boiling point of the liquid
3 is correct
This is an extension of the statement 2. While we decrease the atmospheric pressure, we are also decreasing the boiling point
4 is incorrect
A liquid have a definite volume. When we say a volume is definite, it means the volume is fixed and does not change. The volume of liquids is definite for a particular mass of the liquid and does not change
(1) a beta particle is your answer. Na-24 decays through beta decay, turning a neutron into a proton, electron (beta particle), and an neutrino.
They use fans and air conditioning in the summer because its hot, which means they use energy and in the winter, there is no need because its cold so less energy.
Answer: The wavelength of the x-ray wave is 
Explanation:
To calculate the wavelength of light, we use the equation:

where,
= wavelength of the light = ?
c = speed of x-ray= 
= frequency of x-ray =

Putting in the values:

Thus the wavelength of the x-ray wave is 
B protons are positive atoms and are inside the nucleus
