Answer: particles movement in solid< particles movement in liquids< particles movement in gases.

Explanation:

Atoms are very small, it is not easily seen even with the help of light microscopes. However, We use multiple models of atoms toexplain describe particles of an atom behaviour.

In solids, the particles are packed together tightly in an ordered arrangement. The particles only vibrate about their position in the structure because the particles are held together too strongly to allow movement. Thereby,making the particles MOVE THE LEAST

In liquids, the particles are close together and they move with random motion in the container. The particles move rapidly in all directions but there is more colision between itself even more than particles in gases. This means that the particles here are MORE FASTER THAN THAT OF THE SOLID.

Particles in gases move the FASTEST, more than the particles in solids and liquids. Although, the average speed of the particles depends on their mass and the temperature.

A 10,000 N piano is dropped from the top of a building. When the piano reaches terminal speed…

wel

a). When the piano reaches terminal speed, it is no longer accelerating,
so the net force on it must be <em>zero</em>.

b). If the net force on the piano is zero, the upward force of air resistance on it
must be exactly equal to the downward force of gravity ... <em>10,000 N</em>.

Introduction: The specific heat capacity of a substance is the amount of energy needed to change the temperature of that substan

ki77a [65]

Answer:

A) 8,368 J

B) ) 0.893 J/gºC

Explanation:

The heat gained by the water can be obtained solving the following equation:

$q_{g} = c_{w} * m * \Delta T (1)$

where cw = specific heat of water = 4.184 J/gºC
m= mass of water = 1,000 g
ΔT = 2ºC
Replacing these values in (1) we get:

$q_{g} = c_{w} * m * \Delta T = 4.184 J/gºC*1,000 g* 2ºC = 8,368 J (2)$

Assuming that the heat energy gained by the water is equal to the one lost by the aluminum, we can use the same equation, taking into account that the energy is lost by the aluminum, so the sign is negative: -8,368 J.
Replacing by the mass of aluminum (125 g), and the change in temperature (-74.95ºC), in (1), we can solve for the specific heat of aluminum, as follows:

$q_{l} = c_{Al} * m_{Al} * \Delta T (3)$

⇒ $-8,368 J = c_{Al}* 125 g * (-74.95ºC) (4)$

$c_{Al} = \frac{-8,368J}{125g*(-74.95ºC} = 0.893 J/gºC (5)$

which is pretty close to the Aluminum's accepted specific heat value of 0.900 J/gºC.

Which statement best describes the energy of activation?

Varvara68 [4.7K]

hi <3

i believe the answer would be D, as when the temperature increases the particles have more energy and can overcome the activation energy more rapidly.

hope this helps :)
