Answer:

(a) dew condensing on a leaf

(c) ice cream melting

Explanation:

The process which can be reversed by changing the temperature , i.e. , by increasing or decreasing the temperature , is called the <u>reversible process</u> .

From the question ,  

  • dew condensing on a leaf is a reversible process ,  

As the water on the leaf can be changed to gaseous state by increasing the temperature .  

The process of condensation and evaporation are reversible of each other .

  • Ice cream melting

The melted ice cream can be solidified again by reducing its temperature , hence , it is a reversible process .

  • an egg turning hard when boiled and the batter cooking on a hot griddle

They both are irreversible process , and by changing the temperature , we can not get back the original substance .

What is the wavelength of a photon with an energy of 3.38 x 10-19 J?
irina1246 [14]

Answer:

C. 588 nm

Explanation:

Given parameters:

Energy of the photon  = 3.38 x 10⁻¹⁹J

Unknown:

Wavelength of the photon   = ?

Solution:

The energy of a photon can be expressed as;

     E = \frac{hc}{wavelength}

    hc  = E x wavelength

     Wavelength  = \frac{hc }{E}  

  h is the Planck's constant = 6.63 x 10⁻³⁴m²kg/s

  c is the speed of light  = 3 x 10⁸m/s

  E is the energy  

   Wavelength = \frac{6.63 x 10^{-34} x 3 x 10^{8} }{3.38 x 10^{-19} }    = 5.89 x 10⁻⁷m

Identify the false statement from the following.
LUCKY_DIMON [66]

The false statement from the above is that: Temporary charge imbalances in the molecules lead to London dispersion forces.

<h3>What are the factors that affect London dispersion forces?</h3>

Generally, the factors which affects the London dispersion forces a dispersion force are as follows:

  • Shape of the molecules
  • Distance between molecules
  • Polarizability of the molecules

However, London dispersion forces simply refers to a sort of temporary attractive force formed when electrons in two adjacent atoms occupy positions that make the atoms form dipoles.

So therefore, temporary charge imbalances in the molecules lead to London dispersion forces is a false statement
