What is the substance state at 50 C?
For example, a pressure of 50 kPa and a temperature of −10 °C correspond to the region of the diagram labeled “ice.” Under these conditions, water exists only as a solid (ice). A pressure of 50 kPa and a temperature of 50 °C correspond to the “water” region—here, water exists only as a liquid.
What has a melting point of 50 Celsius?
Melting Points of Elements Reference
| Symbols | Melting Point | # |
|---|---|---|
| 505.06 K | 232.06 °C | 50 |
| 527 K | 254 °C | 84 |
| 544.52 K | 271.52 °C | 83 |
| 575 K | 302 °C | 85 |
Which substance is solid at degrees Celsius?
If both the normal melting point and the normal boiling point are above room temperature, the substance is a solid. Sodium chloride melts at 801°C and boils at 1413°C. Sodium chloride is a solid under normal conditions….
| Density at 20°C | Density at 100°C | |
|---|---|---|
| gas: oxygen | 1.33 g/L | 1.05 g/L |
At what temperature is a substance a solid?
At low temperatures (below 0°C), it is a solid. When at “normal” temperatures (between 0°C and 100°C), it is a liquid.
In what phase is the substance at 50 C and 1atm pressure?
A pressure of 50 kPa and a temperature of 50 °C correspond to the “water” region—here, water exists only as a liquid. At 25 kPa and 200 °C, water exists only in the gaseous state.
Which substance is liquid at 25 degrees Celsius?
Water
Water is a liquid at standard temperature and pressure (25 degrees Celsius and 1 atm, for liquids). Water is is tasteless and odorless.
Which substance is a liquid at a room temperature of 25 C?
Mercury
For science, it’s usually considered to be either 20°C or 25°C. At this temperature and ordinary pressure, only two elements are liquids: Bromine. Mercury.
Are solids at room temperature of 25 degrees?
Most of the metals are solids under “ordinary” conditions (i.e., 25ºC, 1 atmosphere of pressure, etc.), with the exception of mercury (Hg, element 80), which solidifies at -39ºC, and is a freely-flowing liquid at room temperature.
What temperature changes solid to liquid?
32° Fahrenheit
The solid begins to go from a solid state to a liquid state — a process called melting. The temperature at which melting occurs is the melting point (mp) of the substance. The melting point for ice is 32° Fahrenheit, or 0° Celsius.
