Answer:

Average speed of the motorist is 58 km/hour.

Explanation:

Total distance covered by motorist = D = 406 km

Total time taken motorist = T = 7 Hours

The formula of an average speed is given by:

Average speed of the motorist is:

Answer: option # 4, the collisions of the gas particles may result in the transfer of energy.

Explanation:

The kinetic molecular theory (KMT) explains the behavior and properties of gases in terms of the energy, the size, and the motion of the gas particles.

In terms of size, according to the KMT the gases are formed by small particles separated from each other in a vacuum. The volume of the particles is negligible and it is considered that they do not occupy any space.

Since the particles are separated they do not exert either attraction or repulsion to each other.

Regarding the motion, the particles are in constant random motion. They move in straight lines until collide with other particles or with the walls of the veseel. The collisions are elastic (the total kinetic energy is conserved). The kinetic energy may be trasferred between the particles, but the total kinetic energy does not change.

The kinetic energy and the temperature are related: the temperature is a measure of the average kinetic energy of the particles of gas. At a given temperature all the gases have the same average kinetic energy.

Now, check every choice:

1)The gas particles are arranged in a regular pattern:

False. The particles occupy all the volumen and are in random motion.

2) The force of attraction between the gas particles are strong:

False. The particles are separated and they do not exert any force on each other.

3) The gas particles are hard spheres in continuous circular motion.

False. The particles travel in straight until they collide.

4) The collisions of the gas particles may result in the transfer of energy.

True. When particles collide they may transfer kinetic energy but the total kinetic energy is conserved.

Final answer:

In Kinetic Molecular Theory, an ideal gas is described as a collection of widely separated molecules in constant motion, colliding and possibly transferring energy. These molecules do not have a regular arrangement or exert strong forces of attraction. The theory supports the ideal gas law, linking kinetic energy to temperature.

Explanation:

According to the Kinetic Molecular Theory, the correct statement describing the particles of an ideal gas is: 'The collisions of the gas particles may result in the transfer of energy'. In this model, gases consist of widely separated molecules that are constantly in motion and colliding with each other and with the container walls, which can result in energy transfer.

Molecules of an ideal gas are not characterized by a regular pattern of arrangement nor strong forces of attraction between the particles; in fact, the theory assumes that the gas molecules exert no attractive or repulsive forces on each other or the container walls. These collisions are termed elastic as they do not involve a loss of energy.

The Kinetic Molecular Theory accounts for the behavior of gases and also supports the ideal gas law, which articulates a proportional relationship between the average kinetic energy of the gas molecules and the kelvin temperature of the gas.

Answer:

A food product claiming to be sugar free contains  less than 10 grams of sugar per serving.

Explanation:

There are several sugars, such as lactose (milk), fructose (fruits and honey), maltose (beer), sucrose (table sugar), among others. These can be classified into intrinsic sugar, that is the sugar that is part of the composition of foods such as milk (lactose), vegetables or fruits (fructose) and free sugars, which are those added by manufacturers, consumers or cooks.  This last classification includes sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates.

The main difference between them is that eating a large amount of food containing free or added sugar causes a metabolic reaction that increases the risk of being overweight or obese, and of developing diabetes, gout, ulcerative colitis, vascular diseases and caries. However, the consumption of intrinsic sugars does not pose a health risk.  Therefore, the recommendation of the World Health Organization is that the daily consumption of free sugars should be reduced to less than 10% of the total caloric intake, that is, to a maximum of 25g of free sugars per day.

Answer:

the current is carried through the electrolyte by the movement of ions - not electrons.

Explanation:

The reason that an electrolyte has to be molten or in solution is that the current is carried through the electrolyte by the movement of ions - not electrons. In a solid, those ions can't move. It also follows, of course, that an electrolyte must contain ions.
