Explanation:
Water has high specific heat.
The high specificity of water is caused by the hydrogen bond which holds the water molecule together.
When water is heated, due to the arrangement of the atoms in water, the water does not heat up fast, it takes a lot of thermal energy [heating] to heat up water to the point where the hydrogen bonds which hold the water molecules together will break. This property gives water its high heat specificity.
