Why should you never determine the mass of a hot object quizlet?

Why should you never determine the mass of a hot object ? Convection current tend to buoy the object an thus lead to an inaccurately low mass. Moreover, hot objects can damage the balance. Why is it necessary to calibrate a thermometer and volumetric glassware?

Why should one never weigh a hot object select all of the answers that are correct?

IMPORTANT RULES FOR WEIGHING: 1) Do not handle objects to be weighed with bare hands. … 3) Do not weigh hot or cold objects on the balance. Hot objects will give erroneously lower readings due to air buoyancy, while cold objects will give higher readings due to the condensation of water vapor.

How does this experiment illustrate the principle of conservation of matter quizlet?

Does temperature affect the weight of an object?

Yes. If you have absolutely identical objects that have the same weight exactly when they are at the same temperature, then when one object is heated, it will weigh more. … Temperature differences means that there is a different amount of kinetic energy in the motion of the atoms of the two bodies.

Why should you never mass powdered substances directly on the pan of the balance?

Do not place chemicals directly on the balance pan unless they are inert (unreactive) and at room temperature. … The reason for this rule is that many chemicals react with the balance pan. Some attract moisture and cause corrosion. Any residue that sticks to the pan can interfere with weighing.

What is a pico unit?

Pico (unit symbol p) is a unit prefix in the metric system denoting a factor of one trillionth in the short scale and one billionth in the long scale (0.000000000001); that is, 10−12. … Atomic radii range from 28 picometers (pm) for helium to 260 pm for caesium.

Is a zillion a real number?

A zillion is a huge but nonspecific number. … Zillion sounds like an actual number because of its similarity to billion, million, and trillion, and it is modeled on these real numerical values. However, like its cousin jillion, zillion is an informal way to talk about a number that’s enormous but indefinite.
