How would you describe (explain the differences) solids, liquids, and gases to a 4th grader? Be clear please.
musickatia [10]
A solid is an object that has definite shape, volume, and mass. This means that the shape, volume, and mass will never change.

A liquid is something that has definite volume and mass, but it does not have definite shape because a liquid is the shape of its container.

A gas <span>does not have a definite shape, mass, or <span>volume because a gas is able to spread around.</span></span>

<h2>Hello!</h2>

The answer is:

The new volume will be 1 L.

V_{2}=1L

<h2>Why?</h2>

To solve the problem, since we are given the volume and the first and the second pressure, to calculate the new volume, we need to assume that the temperature is constant.

To solve this problem, we need to use Boyle's Law. Boyle's Law establishes when the temperature is kept constant, the pressure and the volume will be proportional.

Boyle's Law equation is:

P_{1}V_{1}=P_{2}V_{2}

So, we are given the information:

V_{1}=2L\\P_{1}=50kPa\\P_{2}=100kPa

Then, isolating the new volume and substituting into the equation, we have:

P_{1}V_{1}=P_{2}V_{2}

V_{2}=\frac{P_{1}V_{1}}{P_{2}}

V_{2}=\frac{50kPa*2L}{100kPa}=1L

Hence, the new volume will be 1 L.

V_{2}=1L

Have a nice day!

A microwave can have a frequency of 3.8 X 1010Hz. How much energy does this microwave give off in joules?
Marina86 [1]

Answer:

2.52 x 10^{-23} J

Explanation:

The energy given off by the microwave can be determined by the application of Planck's energy formula:

E = hf

where: E is the required energy, h is Planck's constant (6.626 x 10^{-34}m^{2}Kg/s), and f is the frequency (3.8 x 10^{10} Hz).

So that;

E = 6.626 x 10^{-34} x 3.8 x 10^{10}

  = 2.51788 x 10^{-23}

Therefore, the energy released by the wave is 2.52 x 10^{-23} J.
