How would you determine the proper number of significant figures of a liquid using a graduated cylinder

Usually you can only go one more than the cylinders markings. So, for example, if your cylinder has markings of 1 mL , then at most you can say like the liquid is at 20.5 mL. Which would be 3 figures for this.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
