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.
Do covalent bonds give water low heat capacity?
Water has a relatively high heat capacity, not a low heat capacity. Heat capacity is the amount of heat energy required to raise the temperature of a substance by a certain amount. Water has a high heat capacity because it requires a lot of energy to raise its temperature. This property of water is due to the strong hydrogen bonds between its molecules, which require a lot of energy to break. As a result, water can absorb or release a large amount of heat without undergoing a significant change in temperature, making it an excellent heat sink. The specific heat capacity of water is the amount of energy required to raise the temperature of a substance by 1 degree Celsius (or 1 Kelvin). Water has a high specific heat capacity because it requires a lot of energy to raise its temperature. This property of water makes it an important factor in the regulation of temperature in living organisms and in the Earth's climate. It is also why water is often used as a coolant in various types of cooling systems, such as in car radiators and air conditioners.
Does water has a high specific heat due to the hydrogen bonding between water molecules?
Because of these slightly polar bonds water molecules need the input of greater amounts of energy to separate molecule from molecule in the rapid motion defining heat and further on to vaporization. A molecule such as methane, CH4, has no hydrogen bonding and has a low specific heat capacity by comparison.
Why is waters specific heat capacity 1.00 cal g C or 4.185 Joules g?
This is water's specific heat capacity because this is the amount of energy needed to heat up the water 1 degree Celsius.
What is the quantity of heat energy required to raise the temperature of a unit mass of a substance?
If the substance is water, this is the kilocalorie (1000 calories). One calorie is the heat to raise one gram of water by 1 deg C. Other substances don't have the same specific heat capacity as water, so you have to correct for that, first find out the heat capacity (specific heat) for the substance you are dealing with.

Why does water have a high and specific heat?
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
Why does water have a specific heat capacity?
Water has a high specific heat because of the hydrogen bonds acting on the molecules. These hygrogen bonds can "store" thermal energy, and this allows water to absorb or release a lot of heat without a large change in temperature.
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)
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.
What is the heat of water?
the specific heat capacity of water is 4200 J / kg °C
What is the difference in specific heat between hydrogen and oxygen molecules?
The molar heat capacity of hydrogen (H2) is 28,835 J/mol/K.The molar heat capacity of oxygen (O2) is 29,378 J/mol/K.
Which has a greater specific heat capacity - water or sand?
Water has a greater specific heat.

Why the specific heat of water is quite large?
