The energy that the water in the bottle absorbed is obtained as 16800 J.
<h3>What is the specific heat capacity?</h3>
The specific heat capacity of the water refers to the energy that is required to raise the temperature of 1Kg of the water by 1 degree.
Now we have the following;
mass (m) = 160 g
temperature change dT = ( 35oC - 10oC)
specific heat capacity (c)= 4.2 J/(g * oC).
Now;
H = mcdT
H = 160 g * 4.2 J/(g * oC) * ( 35oC - 10oC)
H = 16800 J

In my perspective I think its D because Electrical energy is converted to light and heat
Answer: A
Trust me or don’t I just know it
Answer: 10.3 mol/l
Explanation: Molality = concentration c = n/V
Amount of substance n = m/M = 150 g / 58.44 g/mol =
2,5667 mol . c = 2.5667 mol / 0.25 l = 10.2669 mol/l
c =
