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.
Water requires more energy than an equal mass of iron for its temperature to increase by a given amount because water has a greater?
Specific heat capacity. This means water can absorb more heat energy before its temperature increases compared to iron, which has a lower specific heat capacity.
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.
Which Has An Greater Specific Heat Water or Copper?
Water has a greater specific heat capacity than copper. This means that water can absorb more heat energy before its temperature increases compared to copper. This property of water is why it is often used as a coolant in various applications.
Which has a greater specific heat capacity - water or sand?
Water has a higher specific heat capacity than sand. This means that water can absorb and store more heat energy per unit mass without a significant increase in temperature compared to sand. This property of water makes it useful for regulating temperature in environments and organisms.
Does milk boils faster than water?
Water boils faster
In which temperature water has maximum specific heat capacity?
Water has the highest specific heat capacity at 25 degrees Celsius. This means that it can absorb or release a significant amount of heat before its temperature changes, making it an effective heat buffer.
What is the heat capacity of 165g of liquid water?
The specific heat capacity of liquid water is 4.184 J/g°C. To find the heat capacity, you multiply the mass of the water (165g) by the specific heat capacity. So, the heat capacity of 165g of liquid water is 688.56 J/°C.
What is the heat of water?
the specific heat capacity of water is 4200 J / kg °C
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
Which has the greater specific heat capacity- an object that cools quickly or an object of the same mass that cools more slowly?
An object that cools more slowly typically has a greater specific heat capacity. Specific heat capacity is a measure of the amount of heat energy required to change the temperature of a unit mass of a substance, so an object that can retain heat for longer before cooling down has a higher specific heat capacity.
is the specific heat of coconut water and water the same?
No, the specific heat of coconut water is typically lower than that of regular water. Coconut water has a specific heat capacity of around 3.91 J/g°C, while water has a specific heat capacity of around 4.18 J/g°C.
How are the amount of heat transferred and the change in temperature of water related?
Hi, heat transferred = mass x specific heat capacity x rise/fall in temperature If heat is lost then fall in temperature If heat is gained then rise in temperature. More the transfer then greater the difference in temperature.
