Answer:

The Fruit juice should be put in the cooler, because it has the greatest heat capacity and will therefore, absorb the most heat for each degree it increases in temperature.

Explanation:

in order to understand the answer above we need to know what specific heat capacity is

Specific heat capacity can be defined as the amount of heat required to raise the temperature of a unit mass of a substance by one degree

Looking at the specific heat of each substance suggested we see that the fruit juice has a higher specific heat capacity than others this is because it contains a higher amount of water , generally liquid states of substances have a higher specific heat capacity than other states. The specific heat capacity of fruit juice being the highest among the suggested substances means that it can absorb more heat for each degree temperature of refrigerator.

The first-order decomposition of cyclopropane has a rate constant of 6.7 × 10–4 s–1. If the initial concentration of cyclopropan

Ket [755]

Answer:

.864 M

Explanation:

For first order decomposition,

rate constant k = 1/t x ln a / (a - x )

given , a = 1.33 M , t = 644 s , k = 6.7 x 10⁻⁴ , a - x = ? = b( let )

6.7 x 10 ⁻⁴ = 1/644 x ln 1.33/b

ln 1.33/b = 6.7 x 10⁻⁴ x 644 = .4315

1.33 / b = e⁰ ⁴³¹⁵ = 1.5395

b = 1.33 / 1.5395 = .864 M.

How does the velocity, the distance it has fallen and the acceleration of a free falling body change with time?

iragen [17]

The acceleration a free falling body experiences due to gravity will always remain the same. It will always be -9.8 m/s^2.

Thus, the downward velocity of the body will always be increasing (or decreasing, however you want to think about it) because gravity is acting upon it.

The distance the body has fallen will increase faster and faster over time because its velocity is increasing.
