Answer:
0.25J
Explanation:
Given parameters:
Mass of water = 0.2706g
temperature change = 0.216°C
Unknown:
Amount of heat added = ?
Solution:
The quantity of heat added to a substance is given by the expression below;
H = m c Δt
where m is the mass of the body
c is the specific heat capacity
Δt is the temperature change
specific heat capacity is a constant and for water the value is 4.2J/g°C
Input the variables to solve for H;
H = 0.2706 x 4.2 x 0.216 = 0.25J
