Answer:
1·199 J
Explanation:
Given
Mass of water = 0·814 g = 0·814 × kg
Increase in temperature = 0·351 °C
Let the amount of heat added be Q J
Formula for heat added is
<h3>Q = m × s × ΔT</h3>where Q is the amount of heat transferred
m is the mass
s is the heat capacity
ΔT is the change in temperature
Heat capacity of water = 4200 J/kg °C
Applying the formula for heat added
Q = 0·814 × × 4200 × 0·351 = 1·199 J
∴ Amount of heat added = 1·199 J
The periodic table arranges elements in increasing
atomic number from left to right and top to bottom.
Horizontal rows on the periodic table are periods.
Elements in the same period have the same number of
electron shells.
Vertical columns on the periodic table are groups.
Elements in the same group have the same number of
valence electrons.
