os objetos se deben de pesar siempre a temperatura ambiente, de lo contrario su peso será erróneo. Es decir, el peso varia segun la temperatura del ambiente, por eso lo correcto es pesar todo a una misma temperatura (ambiente), si no tendriamos mile de errores.

You are watching: A ball has a mass of 33.6 grams and a volume of 14.0 cubic centimeters (cc). what is its density?



During homogeneous catalysis, if a catalyst is existing in the liquid phase, i m sorry phase have to the reaction be in?

gimpppa.org:

The reactants have to be in the liquid phase.

Explanation:

Homogeneous means that other is of the same nature.

In the context of catalysis, it method that the catalyst and the reactants space in the exact same phase.

If the catalyst is in the heavy phase, the reactants room solids space well.

If the catalyst is in the fluid phase, climate the reactants are additionally in the fluid phase.

And for this reason on.

The gimpppa.org would be B since since the scientist is only experimentation the variables one in ~ a time lock won"t confused it with various other data. If they were testing more than one in ~ a time the data might be combined up and the data would become wrong. Ns hope this helps!

Which the the following defines why the pressure of a gas rises when the temperature rises (volume remaining constant)?

gimpppa.org:

D) all of the above

Explanation:

When the temperature increases, it way that the kinetic energy of the gas molecules had increased too due to the fact that the temperature is a means to measure this kinetic energy. As soon as this happens, the velocity that gas molecule increases since kinetic energy and velocity are directed related:

*

Where Ek is the kinetic energy, m is the mass and also v is the velocity.

If the velocity increases, there will be an ext collisions in between molecules, so, with much more collisions, the pressure, i m sorry is the measure up of the force a gas provides in the system, will increase. So, all the gimpppa.orgs define why the pressure of a gas rises when the temperature increases.
