m = mass of the ice added = ?
M = mass of water = 1.90 kg
= specific heat of the water = 4186 J/(kg ⁰C)
= specific heat of the ice = 2000 J/(kg ⁰C)
= latent heat of fusion of ice to water = 3.35 x 10⁵ J/kg
= initial temperature of ice = 0 ⁰C
= initial temperature of water = 79 ⁰C
T = final equilibrium temperature = 8 ⁰C
using conservation of heat
Heat gained by ice = Heat lost by water
m (T - ) + m = M ( - T)
inserting the values
m (4186) (8 - 0) + m (3.35 x 10⁵ ) = (1.90) (4186) (79 - 8)
m = 1.53 kg
Based on the number of positive and negative charges
<u>Explanation</u>:
- In a positive charge particle, the number of proton is higher than the number of electron. Due to this fact alone, we can come to the conclusion that positive charge consists of more number of protons than electrons.
- In a negative charge particle, the number of electron is higher than the number of proton. Due to this fact alone, we can come to the conclusion that negative charge consists of more number of electrons than protons.
