Answer 1
I don’t know the exact answer but this information may help. :) The sun transfers energy to the grass by radiation, which they turn into energy through photosynthesis. They have 100% of the energy in a food chain. Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
Answer 2
Energy is transferred into the food chain since the sun produces energy to plants and with that animals eat plants and so on.

Answers

the 1 st one you said i think

When heat is removed as a gas turns into a liquid. In liquid state molecules are more  closer than in gases. Hence, option a is correct.

What is a phase change ?

The interconversion between states of matter is called phase change. The conversion of solid to liquid, liquid to gas, etc. are examples of phase changes.

In solid state, particles are closely packed and cannot move apart. The strong intermolecular forces can be weaken by applying energy. In liquid state, particles have some more space to low and in gases they are far apart.

When gases phase converts to liquid, the heat is removed from the system and make make the intermolecular forces stronger to bring molecules closer.

It loses energy.

I believe it becomes less dense, bc when you heat something it’s molecules spread further apart.
Yes it becomes less dense because when the water molecules are hot it tends to go around more faster but if it was cold it would stay still. Just like us humans would do.

Answers

since you have an internal body temperature, which circulates warmth, anything cold that is in contact with your body will start to ‘decrease’ that internal body temp (in that particular part of the body) the hot energy is transferred to the cold -> the cold energy is transferred to the hot

ex: you grab an ice cube, the ice cube begins to melt because the warmth of your hand melts it, afterwards your hand is cold

someone pls help me i need it by today ty :)

Answer:

In covalent bonding, the octet rule is important because sharing electrons gives both atoms a full valence shell. As a result, each atom can consider the shared electrons to be part of its own valence shell.

In covalent bonding, the octet rule is important because sharing electrons gives both atoms a full valence shell.

What are chemical bonds?

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds.

The octet rule states that atoms are at their most stable when they have the electron configuration of a noble gas.

This means having eight outer shell electrons. Because of this, atoms tend to try and gain or lose electrons until they have eight electrons in their outer shell.

As a result, each atom can consider the shared electrons to be part of its own valence shell.
