Answer:

a. increase

Explanation:

Based on the kinetic molecular theory of gases, the average kinetic energy of the system will increase.

  • The average kinetic energy is heat
  • If temperature increases, heat of a system will also rise.
  • According the kinetic molecular theory "the temperature of the gas is a measure of the average kinetic energy of the molecules"

Therefore, due to the increase in temperature, the average kinetic energy of the system increases.

Can the law of conservation of mass be applied when cooking? In one to two sentences, explain why or why not. Please give an exa
zlopas [31]

The law of conservation of mass is must be applied when cooking.

<h3>What is conservation of mass?</h3>

Law of conservation of mass states that mass of any substance will change into another form without any loss of mass, means destroying of mass is impossible.

When we cook food then mass of conservation is applied there, for example we are boiling pulses with water then in that case the amount of formed liquid pulses is equal to the initial mass of solid pulse with water.

Hence law of conservation of mass is applicable during cooking.

If our eyes could see a slightly wider region of the electromagnetic spectrum, we would see a fifth line in the Balmer series em
erica [24]

Answer: Wavelength  associated with the fifth line is 397 nm

Explanation:

E=\frac{hc}{\lambda}

\lambda = Wavelength of radiation

E= energy

For fifth line in the H atom spectrum in the balmer series will be from n= 2 to n=7.

Using Rydberg's Equation:

\frac{1}{\lambda}=R_H\left(\frac{1}{n_i^2}-\frac{1}{n_f^2} \right )\times Z^2

Where,

\lambda = Wavelength of radiation

R_H = Rydberg's Constant =10973731.6m^{-1}

n_f = Higher energy level = 7

n_i= Lower energy level = 2 (Balmer series)

Putting the values, in above equation, we get

\frac{1}{\lambda}=10973731.6\times \left(\frac{1}{2^2}-\frac{1}{7^2} \right )\times 1^2

\frac{1}{\lambda}=2.52\times 10^{6}m

\lambda}=3.97\times 10^{-7}m=397 nm      1nm=10^{-9}m

Thus wavelength λ associated with the fifth line is 397 nm

The main type of attractive forces between molecules of carbon tetrabromide (cbr4) are:_______
romanna [79]

Answer:

Vanderwaals forces

Explanation:

CBr4 is a nonpolar molecule, nonpolar molecules usually possess vanderwaals forces between their molecules as their main attractive force.

CBr4 is nonpolar because the tetrahedral arrangement of the C-Br bonds cancel out the individual dipole moments of each C-Br bond thereby making the compound nonpolar, hence the answer above.

Which best describes the effect of jj Thomson discovery
beks73 [17]
JJ Thomson discovered electrons using the cathode ray. Electrons are negatively charged particles that orbit around the nucleus of an atom. Finding out that there was a negative charge to balance out the positive charge. This later helped develop Hund's Rule and the Pauli Exclusion Principle.
