The amount of heat needed to increase the temperature of a 1-kilogram substance by 1°C is known as the specific heat of the substance.
the formula for specific heat of a substance is given as
c = Q/(m ΔT)
where Q = Heat required to change the temperature by 1°C
m = mass of the substance
ΔT = change in temperature.
the units of specific heat is given as Joules/(kilogram °C)
Answer:
134.75935 seconds
Explanation:
m = Amount of water = 240 mL
c = Specific heat of water = 4.2 J/mL °C
= Change in temperature = 
t = Time taken
P = Power = 1100 W
E = Pt
Efficiency = 51 %
So, Energy = 0.51Pt
As energy is conserved
Q = 0
The it takes to raise the temperature is 134.75935 seconds
Answer: A) Current
Current is the flow of electrons. The more electrons that flow, then the higher the amperage which measures this flow. If the current is high enough, then the electrical shock may cause damage of some kind.
"Amperage" is abbreviated as "Amp". You may see something like "milliamp" when it comes to measuring this amperage.
The ocean's water's density increases when it gets colder.
The molecules in the water get colder and move less, causing it to densify... As though it were freezing (though we all know the ocean hasn't ever frozen)
