Answer:

The amount of time required to rise the temperature of 0.50 liter of water from 0.0 c to 10.0 c is 19 seconds

Explanation:

1100 J/s is the energy supplied so, we have to set, the energy to that ΔT, which is 10°C (10°-0°)

Q = m . C. ΔT

Q =  500g . 4,186J/g°C . 10°C

Remember the water density is 1g/mL, so if we have 0,5 L, we should get the convertion to g. (1ml = 1x10*-3 L)

1x10*-3 L ____ 1 g

0,5 L _____ (0,5 L . 1 g)/ 1x10*-3 L = 500g

4,186J/g°C, this value is known as specific heat of water. It is a known value.

Q =  500g . 4,186J/g°C . 10°C = 20930 J

Now the final rule of three:

1100 J supplies at _____ 1 second

20930 J supplies at _____ (20930 J . 1 s) / 1100 J =19,02 s

Which two layers are part of the thermosphere?
borishaifa [10]

Answer:

exosphere and ionosphere.

Explanation:

very high up,the earth's atmosphere becomes very thin. the region where atoms and moleculesescape into space is referred to as the exosphere. exosphere is on top of the thermosphere.

scientists what is called the ionospherean extension of the thermosphere. so technically, ionosphere is not another atmospheric layer.

Which of the following would NOT diffuse through the plasma membrane by means of simple diffusion?1 oxygen2 glucose3 a steroid h
Mumz [18]

Answer:

Option 2= Glucose

Explanation:

Cell membrane is made up of two phospholipid layers and each contain phosphate head and fatty acid or lipid tails. the head is present between the outer and inner boundaries and tail is present in between. The small non- polar molecules can pass the membrane through simple diffusion. This lipid tail restrict the passage of polar molecules including water soluble substances like glucose. However, transmembranes are present that allow the molecules to inter that are blocked by the tails.

Facilitated diffusion:

it is a type of diffusion in which caries protein without using the cellular energy shuttle the molecules to the cell membrane. Glucose is bind on the carrier protein ,change the shape and transport it from one to another side of membrane. In order to absorb the glucose red blood cells use this kind of diffusion.

Primary active transport:

The cells that are present along small intestine use this type of transport to pump the glucose inside the cell. The primary active transport require energy to transport the glucose inside.

Secondary active transport:

It is another method of transport of glucose into the cell. This method can not use ATP but it is based on concentration gradient of the sodium that provide electro chemical energy for the glucose transport.

Electron affinity is the measure of the attraction of an electron toward an isolated gaseous atom. When an electron is added to
zhuklara [117]

False

Explanation:

Electron affinity is negative when energy is absorbed and it is positive when energy is released.

Electron affinity is defined as the energy released in adding an electron to a neutral atom in the gas phase.

It is a measure of the readiness of an atom to gain an electron.

In a reaction where energy is released, electron affinity is usually positive. These reactions are called exothermic reactions.

Endothermic reactions in which energy is absorbed have negative electron affinity values.
