Resistance Temperature Detectors (RTD) measure the temperature by Group of answer choices The change in electrical resistance in pure metals as a function of temperature The change in electrical resistance in ceramics or polymers as a function of temperature The conversion of a temperature change to mechanical displacement The change in liquid volume as a function of temperature

2b2t

explanation:

2b2t

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.  

the answer is d. matter from the air combined with the steel wool.
