The triple point of water is 273.1598 K or 0°C at 611.73 pascals of pressure. If ice is heated at pressures below the triple point, what will be the result

Athe ice melts but the water never boils

Bice changes to a liquid and then to a gas

Cthe ice passes directly into the gaseous state

Dthe ice remains solid at pressures lower than the triple point

At pressures below the triple point, a solid "sublimes" ... When it's heated, it turns directly into gas, without ever being a liquid. We never see water do that, because the triple point pressure of water is so low ... less than 1% of the normal atmospheric pressure that we're used to. It's actually pretty close to the atmospheric pressure on Mars. So on Mars, ice cubes would behave like 'dry ice' acts here ... You'd see a cloud swirling around it and then disappear, as the ice turned to water vapor. But there would never be a puddle.

Answer:

c) the ice passes directly into the gaseous state.

Explanation:

Since the pressure decreases, the molecules of water can jump directly from solid to gas because there is any atmospheric pressure that maintain them sticky.
