specific heat capacity

• water can resist (buffer) changes in temperature because the hydrogen bonds between water molecules can absorb a lot of energy
• water has a high specific heat capacity - it takes a lot of energy to heat it up
• water doesn't experience rapid temperature changes which makes water a good habitat because the temperature under water is likely to be more stable than on land
• water inside organisms maintains at a fairly stable temperature because of water's high specific heat capacity, helps to maintain a constant internal body temperature
