Classify the statements based on whether they describe volumetric glassware, such as volumetric flasks, pipets, and burets, or routine glassware, such as Erlenmeyer flasks, graduated cylinders, and beakers. 1. lower price
2. smaller change in size and volume with temperature change
3. more resistant to strong acids and bases
4. more accurate volume measurement
5. used for storing and handling solutions

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

girl imma just put my comment here because i need a couple point okurrttt

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
