6. Describe the energy inputs and outputs for the campfire. Use the law of conservation of energy to construct a valid qualitati
Doss [256]

Answer:

Energy in the campfire originates from the potential chemical energy of the wood, before it is burnt to warm and give light around the campfire.

Explanation:

For a camp fire, the energy input is in the form of the potential chemical energy, stored up in the firewood used to fuel the flame.

The energy output is in the form of heat energy that the campfire radiates all around, light energy given off from the flame, and a little bit of sound energy, heard in the cracking of the firewood as they burn in the flame.

chemical energy ⇒ heat energy + light energy + sound energy

Study the graph in Figure 6.32 and answer to these questions. (see attached image)
Dimas [21]

Hey there :)

We can see that the solubility of salt increases with increasing temperature. This happens with most substances.

To find out the maximum mass of copper sulfate that can be dissolved in water at these temperatures, just interpret the graph.

Considering Y-axis as g copper sulfate/100 g water and the X-axis as the temperature in °C:-

<u>1)</u>

a: <u>0 °C - 14 g of copper sulfate/100 g of water</u>

b: <u>50 °C - 34 g of copper sulfate/100 g of water</u>

c: <u>90 °C - 66 g of copper sulfate/100 g of </u><u>water</u>

<u>2)</u> From the graph, we can infer that temperature affects the solubility of the salt.

The ____ connects the left and right sides of the cerebrum
Fofino [41]

Answer:

The left and right hemispheres of the cerebrum are connected by the Corpus Collosum.

Explanation:

The corpus collosum is a thick band of neurons that divides the cerebral cortex lobes into the left and right hemisphere. The corpus callosum allows for both hemispheres to communicate and transfer information! The primary function of the corpus callosum is to integrate sensory, motor, and cognitive performance between the cerebral cortex.  

Ins severe cases of epileptic seizures, a corpus callosotomy is performed, which cuts the corpus callosum in half. This prevents the seizures from becoming more severe, and the brain can reprogram, through neuroplasticity.
