First, we determine the energy required to melt one gram of ice. This is given by:
Energy = mass * latent heat of fusion
Energy = 1 g * 334 J/g
Energy = 334 J
Next, we use Planck's equation which is:
Energy = number of photons * Planck's constant * speed of light / wavelength
334 = n * 6.64 x 10⁻³⁴ * 3 x 10⁸ / 5.49 x 10⁻⁶
n = 9.20 x 10²¹
9.20 x 10²¹ photons need to be absorbed by the ice.
Answer:
now this area isn't my expertise so take this with a grain of salt but I believe its about 91125 g
Explanation:
8 cm is about 45g cube that and its 91125 g
Electrolyte solutions are substances that give ions when dissolved in water. <span>These solutions </span>conduct electricity<span> due to the mobility of the positive and negative ions, which are called cations and anions. Hope this answers the question. Have a nice day.</span>
Because it's oil and oil always sits on top of water
A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
