Question

The freezing point and boiling point of a substance 'P' are -220 degrees Celsius and -185 degrees Celsius respectively. At which range of temperature will the substance 'P' exist in the form of a liquid?

Answer 1

Answer:

Matter typically exists in one of three states: solid , liquid , or gas . The state a given substance exhibits is also a physical property. Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids. Most metals exist as solids at room temperature. All substances can exist in any of these three states. In addition to existing in one of the three states, matter can also undergo a change of state. A change of state occurs when matter is converted from one state to another state for example when a liquid is converted to a gas or a solid is converted to a liquid.
