Respuesta :
The temperature of boiling liquid will be 78°C.
To find the correct answer, we need to know about the upper and lower fixed points of the thermometer.
How to find the temperature of boiling liquid?
- The lower fixed point is measured by the melting temperature of pure water.
- Given that, the fundamental interval is 25cm, which is the separation between the upper and lower fixed points.
- We have the equation for the temperature as,
[tex]T=\frac{x-x_0}{x_{100}-x_0} *100[/tex]
where,
[tex]x=[/tex] length of liquid at T temperature = 19.5cm.
[tex]x_0=[/tex] length of liquid thread at ice point = 0°C
[tex]x_{100}=[/tex] length of liquid thread at steam point = 25 cm.
- Substituting values, we get,
[tex]T=\frac{19.5-0}{25-0}*100\\ T=0.78*100=78^0C[/tex]
Thus, we can conclude that, the temperature of boiling liquid will be 78°C.
