Which statement best describes the collisions of gas particles according to the kinetic-molecular theory?​
allochka39001 [22]

B. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.

Explanation:

The best statement that describes the collision of gas particles according to the kinetic-molecular theory is that as particles travel in straight lines, their paths sometimes meet and then they bounce apart with no gain or loss of energy.

  • The kinetic molecular theory is used to explain the forces between molecules and their energy.

One of the postulate suggests that, when molecules collide with each other, or with the wall of the container, there is no loss or gain of energy.

  • Molecules are independent of one another and that forces of attraction and repulsion between molecules are negligible.

ara h 6 complements ara h 2 as an important marker for ige reactivity to peanut audrey e. koid,† martin d. chapman,†
frez [133]

Purified Ara h 6 will be helpful for research into the immunological mechanisms underlying peanut allergy, including molecular and cellular studies, diagnostic IgE antibody testing, and clinical trials.

1.4% of children and 0.6% of adults in the United States suffer from the food allergy peanut. Approximately 1.8% of youngsters in the UK are allergic to peanuts. Food allergies to milk, eggs, and wheat are often outgrown by children, while allergies to peanuts are more persistent and frequently last into adulthood. As little as 0.4 g of peanut is required to cause milder allergic reactions like rashes, angioedema, and gastrointestinal problems. However, peanut is also one of the leading causes of severe, sometimes fatal anaphylactic reactions.

The metal tantalum becomes superconducting at temperatures below 4.483 K. Calculate the temperature at which tantalum becomes su
masha68 [24]

Answer:

The correct answer is "-268.667°C".

Explanation:

Given:

Temperature,

= 4.483 K (below)

Now,

The formula of temperature conversion will be:

⇒ T(^{\circ} C)=T(K)-273.15

By putting the values, we get

⇒            =4.483-273.15

⇒            =-268.667^{\circ} C

Thus the above is the correct answer.
