volume‚ mass‚ density‚ and specific gravity of solids and liquids with accuracy. Equipment: Students use the electronic balance to measure the mass of metals‚ pipettes‚ and pipettes holding liquids. The user presses the tare button to set the scale back to 0 g‚ and then places the metal or pipette onto the balance. The result is rounded to two decimal places. The graduated cylinder is used for measuring volume of a liquid or water displaced by a solid. The students look at lines‚ at eye level‚

and talked in a public speech to all people. She wants to change the habits of adults and children. Severn says‚ that she found fish with cancer. Is this the way we want to eat fish? We really have to think of what we can make better in waste seperation. So if for instance plastic is thrown in the sea‚ the fish will eat the plastic‚ and we eat the fish. Horrible! Another problem is the buying of unnecessary things. We buy and throw away. Why don´t we think of what we really need? In my opinion

differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available. This diagram shows the nomenclature for the different phase transitions. More recently‚ distinctions between states have been based on differences in molecular interrelationships. Solid is the state in which intermolecular

Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula of the unknown was determined through the process of elemental analysis by using molecular weight and

evaporation • Solids have the least random molecular motion • Under the same conditions of pressure and temp a liquid differs from a gas because the molecules of the liquid take shape of the container they are in. • The phase change in which a solid becomes a liquid is known as the melting. Liquid to gas is evaporation. Gas to liquid is condensation. Liquid to solid is freezing. Solid to gas is sublimation. Gas to solid is deposition. • The temp of a liquid during boiling increases
