on earth 81times more mass
We know, the weight of an object on moon weighs 1/6 on that of Earth.
Given weight = 12 kg
Weight on moon will be = 1/6 × 12
= 2 kg.
NOTE : Mass is a Constant.
thermometry is the science and practice of temperature measurement. any measurable change in a thermometric probe (e.g. the dilatation of a liquid in a capillary tube, variation of the electrical resistance
of a conductor, of the refractive index in a transparent material, and so on) can be used to mark temperature levels, that should later be calibrated against an internationally agreed unit if the measure is
to be related to other thermodynamic variables (if the measure is only needed to establish an ordering in
thermal levels, no calibration is required).
thermometry is sometimes split in metrological studies in two subfields: contact thermometry and non- contact thermometry. thermometers measure their own temperature, not that of the surroundings except if in thermal equilibrium. as there can never be complete thermal uniformity at large, thermometry is
always associated to a heat transfer problem with some space-time coordinates of measurement, given rise to time-series plots and temperature maps (profiles, if one-dimensional).
temperature is one of the most measured physical parameters in science and technology; typically for process thermal monitoring and control. but thermometry is not only applied to measuring temperatures for thermal control, but as an indirect measure of many material properties like thermal capacities and enthalpy changes (by thermal analysis), relative humidity (by means of wet bulb or dew-point temperatures), thermo-optical properties and other radiation characteristics (e.g. for the radiation budget of a planet), etc.types of thermometric
