Gas hydrate surrounds hydrocarbon molecules with a cage structure consisting of water molecules. When vibration is applied to the cage structure given by UHF to microwave irradiation, the basket is break by the energy, because, gas hydrate is in the metastable energy states. It is like pushing a balloon with a needle. Artificial butane hydrate models revealed that the temperature raised with small energy than expected. The complex permittivity measurements were also conducted on water, ice and butane hydrates. The hydrate concentration showed intermediate between water and ice. The existence of hydrate is strongly involved in microwave absorption in the low temperature range. A hypothesis will be proposed that microwave perturbation break the cage structure of the clathrate hydrate and that the enthalpy difference between the destroyed subsumed hydrate and the ice structure has changed into heat.
