A person can tell if their home heat pump thermostat is working by setting the temperature a few degrees above or below ambient to see if it kicks on. A thermometer can be used to verify the temperature.
An acid has a pH below 7 and a base had a pH above 7.

Temperature can be measured with a thermometer.
You can use a thermometer or a weather app on your smartphone to tell the temperature outside.

Which temperature scale are you using. ' Celcius, Fahrtenheit or Kelvin'? 50 o C is half way to boiling point of water, as a ambient temperature is is extremely hot. 50 oF is a moderately cool temperature. 50K is below the boiling point of oxygen and nitrogen.
The temperature may be above normal.
Since you didn't tell us the point given below, we can't answer this accurately.
Positive implies above the x-axis or to the right of the y-axis; negative implies below the x-axis or to the left of the y-axis.
The question as posed has no meaning - nothing spontaneously expands. Hydrogen is, at room temperature, above its Joule-Thompson inversion point. It's hard to tell if that's what you were trying to ask or not.
The temperature will be either the boiling point (if liquid and vapor is present) or it will be the melting/freezing point (if liquid and ice is present)
mealting point
After the measurement of the temperature at the change of phase between liquid and gas phases.
An acid has a pH level below 7 whereas a base has a pH level above 7.
An acid has a pH below 7 and a base had a pH above 7.
When it is impossible to dissolve any salt further at a given temperature.
