No, it decreases.
No, it decreases.
Yes, the hardness of ice increases as the temperature decreases.
The temperature decreases
atmospheric
It will increase the surface tension of water hence temperature decreases. If you add phenol to water temperature increase as it decreases the surface tension.
The temperature decreases with altitude.
An increase in temperature usually causes an increase in volume. Since the mass doesn't change, density decreases. tt
Pressure increase when temperature increase.
It doesn't, it decreases.
surface tension decreases with the increase of temperature
viscosity decreases with increase in temperature
