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
They both conduct electricity at least partially
This would be the downward movement of water. It begins flowing and continues in a downward movement moving throughout,
Answer: The actual name Teflon® is a brand/trademark name of the DuPont Corporation used
Explanation:
D. A ll of the above. catalyst reduces the activation energy thereby making the reaction faster. an increase in temperature increases the kinetic energy and no of collisions making reaction faster for an endothermic reaction while decrease in temperature favors an exothermic reaction.
increase in concentration increases the molecules reacting so the reaction is faster and vice versa.
