For calibrating a thermometer, which points are taken as fixed points?

How a thermometer is calibrated?

The length of a mercury column in a mercury-in-glass thermometer is 25 mm at the ice point and 180 mm at the steam point. What is the temperature when the length is 60 mm?

The speed v of particle moving along a straight line, when it is at a distance x from a fixed point on the line is given by v^2= 108 x - 9x^2 . Then magnitude of its acceleration when it is a distance 3 metre from the fixed point is

Range of temperature in a clinical thermometer, which measures the temperature of human body, is

What is ice point and steam point?

Consider a liquid at rest in a container which opens into atmosphere. At any point A at a depth h below the surface of the liquid, (i) the gauge pressure at point A is rho gh. (ii) the gauge pressure at point a is P _(a)+rhogh. (iii) The pressure at point A is rhogh. (iv) The pressure at point A is Pa + rho gh. The correct alternative is

A _____ is fixed at focal point of the objective, which reflects the collected rays to eyepiece.

A resistance thermometer has resistance 95.2O mega at the ice point and 138.6 Omega at the steam point. What resistance would be obtained if the actual temperature is 27 ^@C ?

The pressure reading in a thermometer at steam point is 1.367 xx 10^3 Pa. What is pressure reading at triple point knowing the linear relationship between temperature and pressure?

A resistance thermometer has resistance 95.2 Omega at the ice point and 138.6 Omega at the steam point. What resistance would be obtained if the actual temperature is 27^@ C ?
