Loess helps to form very fertile soil. Please select the best answer from the choices provided T F
Feliz [49]

The given statement is true.  

A classic, predominantly silt-sized sediment, which is produced due to the gathering of wind-blown dust is known as loess. About 10 percent of the land region of the Earth is covered by loess or identical sediments. The loess seems to form into very rich soils. Under suitable climatic circumstances, it is one of the most agricultural productive terrains around the globe.  

The soils formed by loess seems to be extremely drained. It is considered that the fertility of the loess soils is mainly because of porosity and cation exchange capacity.

When a boy and his friends arrive at a barbecue, they offer to help their friend cook. They place meat and vegetables from the r
Ostrovityanka [42]

A. The kinetic energy of the food particles increased, causing the food temperature to rise.

B. The thermal energy of the food increased

Explanation:

The grilling of the meat increased the thermal energy which cause the kinetic energy of the food particles to increase thereby causing the temperature of the food to rise.

Heat is a form of energy known as thermal energy. It results from the difference in temperature between two bodies.

When a body is heated, the particles of the medium if solid as in the case of the meat begins to vibrate about their fixed point.

Temperature is directly proportional the average kinetic energy of a particle and so the particles gain more kinetic energy.

A marshmallow has an initial volume of 0.027 L at standard pressure (1.0 atm). If the marshmallow is placed in a vacuum chamber
MatroZZZ [7]

Answer:

The pressure inside the chamber is 0.132 atm

Explanation:

Step 1: Data given

The initial volume = 0.027 L

The initial pressure = 1.0 atm

The volume changes to 0.205 L

Step 2: Calculate the pressure

P1*V1 = P2*V2

⇒with P1 = the initial pressure = 1.0 atm

⇒with V1 = the initial volume = 0.027 L

⇒with P2 = the changed pressure = TO BE DETERMINED

⇒with V2 = the changed volume = 0.205 L

1.0 atm *0.027 L = P2*0.205 L

P2 = 0.027/0.205

P2 = 0.132 atm

The pressure inside the chamber is 0.132 atm
