Answer:
The new volume of the balloon be .
Explanation:
We have,
Initial volume is 556 cm ³
The temperature of the balloon decreases from 278 K to 231 K.
We need to find the new volume of the balloon if the pressure is constant.
The Charles law states that at constant pressure, the volume of gas is directly proportional to its temperature i.e.
, P is constant
So, the new volume of the balloon be .
Answer:
4.85 x 10⁻¹⁹J
Explanation:
Given parameters:
Wavelength = 410.1nm

The energy of the violet light = ?
Solution:
The energy of a wave can be derived using the expression below;
E =
h is the planck's constant
c is the speed of light
Insert the parameters and solve;
E = = 4.85 x 10⁻¹⁹J
