The thermal conductivity of ice at 0°C is approximately ______ times the thermal conductivity of water at the same temperature, indicating that in the same environment, ice can change its temperature faster than water.
举一反三
- Under the same ambient temperature, the temperature changing rate of ice is much higher than that of water.
- In agricultural production, the theoretical basis of "Adjusting Temperature with Water" is ( ). A: Water temperature is easy to control; B: Water has a larger heat capacity; C: Water has a larger thermal diffusivity.
- Under the same conditions, fresh water evaporates faster than sea water.
- 3. The three-phase point of water is a temperature and pressure condition under which water, ice and steam can coexist. The corresponding temperature is 0.01℃. Under this temperature, the external pressure of water is（ ） A: 101.325kPa B: 0.6106kPa C: 100kPa D: 1000kPa
- The water activity of ice is smaller than water.
