List the advantages of ethanol thermometer over other liquid thermometers.

Write the quadrants in which the following points lie:

$\left(-4,7\right)$

The resistance of a thermistor at $0°\mathrm{C}$ is $2000 \mathrm{\Omega }$. At $100 °\mathrm{C}$ the resistance falls to $200 \text{Ω}$. When the thermistor is placed in water of constant temperature, its resistance is$620 \mathrm{\Omega }$.

Assuming that the resistance of the thermistor varies linearly with temperature, calculate the temperature of the water.
