Intermolecular forces exists between molecules of the same or different kinds. Water has a dipole moment hence it can interact effectively with the ions in NaCl. This leads to an ion dipole interaction that results in the dissolution of NaCl in H2O.

NaCl is a solid and water is a liquid. Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O.

Hence, the best argument that compares the intermolecular interactions in water and NaCl is; salt is a solid and water is a liquid, so water has stronger intramolecular forces.

If the mass of an object is 6 lbm, what is its weight, in lbf, at a location where g = 32.0 ft/s2?

Solnce55 [7]

Using formula:

$w = m\times g$ -(1)

where w is weight of object,

m is mass of the object, and

g is the acceleration of gravity.

mass, m = 6 lbm (given)

acceleration of gravity, g = $32.0 ft/s^{2}$ (given)

Now, substituting the values in equation (1):

$w = 6 lbm \times 32 ft/s^{2} = 192 lbmft/s^{2}$

Since, $1 lbf = 32.174 lbm ft/s^{2}$

So, $w = 192\times \frac{1}{32.174 lbf}$

$w = 5.976 lbf$

Hence, the mass of an object is 5.976 lbf.

In this section, include a summary of how your Rube Goldberg device design works from start to finish to complete a task. Your R

anyanavicka [17]

The energy conversions in the Rude Goldberg device design is as follows:

a quartz falls off from the roof: potential to kinetic
the quartz hits and lift a soda bottle: kinetic to potential
The soda bottle moves hits a battery: potential to kinetic
a battery which slides along into a torch that lights up: chemical to light

<h3>What is a Rube Goldberg device?</h3>

A Rube Goldberg device uses a set of reactions that work in succession with one event triggering the next event in the form of a chain reaction until the final event is completed.

The Rude Goldberg device design is as follows:

The design is of a unit that produces light when a quartz falls off from the roof. It then hits a plastic soda bottle and its velocity is converted into potential energy used to lift a soda bottle. The soda bottle then on rising hits a battery which slides along into a torch which then light up.

In conclusion, Rude Goldberg devices shows various forms of energy conversion.
