The difference between oil and water is that water has stronger intermolecular bonds thus molecules interact with each other more readily when compared to non polar compounds such as oil (where particles behave independently). Thus waters high heat capacity reflects on its nature of having higher interaction between particles when compared to oil.

What is q equals mC delta T?
How heat is calculated in thermodynamics. Heat = mass x specific heat capacity x change in temperature.
In the equation Q mcΔT c represents .?
The specific heat of the substance being heated.
Is it possible to design a machine that has an efficiency that is greater than 100 percent?
An ordinary domestic heat pump appears to have an efficiency of up to 300% or so. That is it will deliver 3kw of heat for each 1kw of electricity it consumes. But that is illusory because it extracts the extra heat from the water vapour in the air. So in real life, the laws of physics win out.
How many calories to raise 1 quart of water 38 degrees?
A quart of water is 946.35 cubic centimeters and since density of water is 1 gram per cubic centimeter the weight of a quart of water is 946.35 grams. Heat required = (mass) x (specific heat of substance) x (temperature differential) In our case it would be 946.35 x 1 x 38(assumed degrees centigrade) = 35961.3 cals
What is the measure of how much heat will raise the temperature of 1 kg of a substance by 1 degrees c?
The specific heat of the substance.
Which has a greater specific heat capacity - water or sand?
Water has a greater specific heat.
How is specific heat of a substance different from the heat capacity?
Imagine 1 kg of water. This has a heat capacity. Now if you have 1000kg of water the heat capacity is obviously greater. The Specific Heat Capacity is a material constant. It specifies a set quantity. For water it is 4.184 kiloJoules per kilogram per Kelvin.
Water requires more energy than an equal mass of iron for its temperature to increase by a given amount because water has a greater?
Water has a greater specific heat capacity.
In which temperature water has maximum specific heat capacity?
The specific heat capacity of water does not change much within-phase (ie, as a solid it has one specific heat capacity, as a liquid/gas it has another)
Does milk boils faster than water?
Water boils faster
Which Has An Greater Specific Heat Water or Copper?
Water has.
Does hydrogen or water has high specific heat capacity?
Water has a MUCH higher specific heat than hydrogen.
Why does water have a greater specific heat over then sand?
water has a greater specific heat than sand becasue it takes longer to heat up than sand does
What is the heat of water?
the specific heat capacity of water is 4200 J / kg °C
Which substance having high specific heat capacity?
A common substance with a high specific heat is water. There are a few substances that have a higher heat capacity than water, though, such as lithium and ammonia.
What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
What is the specific heat capacity of sea water?
