How much thermal energy does it take to raise the temperature of 4.5 kg of
Romashka [77]

The amount of thermal energy needed is 626.6 J

Explanation:

When a certain amount of heat energy Q is supplied to a substance, the temperature of the substance increases according to the equation

Q=mC_s \Delta T

where

m is the mass of the substance

C_s is the specific heat capacity of the substance

\Delta T is the change in temperature

In this problem,

m = 4.5 kg is the mass

C_s = 1.68 kJ/kg^{\circ} is the specific heat capacity of the substance

\Delta T = 97-12=85^{\circ}C is the change in temperature of the substance

Solving for Q,

Q=(4.5)(1.68)(85)=626.6 J

(Note that the substance cannot be water, since specific heat capacity of water is 4.18 kJ/kg^{\circ}C

k0ka [10]

One phenomenon which well presents the idea of wave particle duality is the photoelectric effect.

<h3>What is wave particle duality?</h3>

The term wave particle duality has to do with the fact that a wave can behave sometimes as a wave and sometimes as a particle. This was well established by the work of De Broglie.

One phenomenon which well presents the idea of wave particle duality is the photoelectric effect.
