3. A gas absorbs 45 kJ of heat and does 29 kJ of work. Calculate AE.
Answer:
∆E = 16 KJExplanation:
Given:
A gas absorbs 45 KJ of heatWork done = 29 KJCalculation:
∆E = q + w
∆E = 45KJ + (-29KJ)
∆E = 45KJ - 29KJ
∆E = 16KJ
A gas absorbs 45 kJ of heat and does 29 kJ of work. The activation energy AE is 16 kJ.
What is activation energy?Activation energy is defined as the atoms or molecules must be activated with the least amount of energy possible in order for them to undergo chemical transformation or physical transport.
It is also defined as the bare minimum of energy required for compounds to undergo a chemical reaction.
Activation energy is important because they accelerate chemical processes without being eaten or irreparably changed by the process.
They speed up reactions without changing the balance between reactants and products.
Given gas absorbed = 45 kJ
Work = 29 kJ
ΔE = q + w
ΔE = 45kJ + (-29kJ)
ΔE = 16 kJ
Thus, a gas absorbs 45 kJ of heat and does 29 kJ of work. The activation energy AE is 16 kJ.

“Our knowledge of the properties and laws of physics shows no signs of approaching its ultimate boundaries. . . This increasing physical knowledge is now, rapidly converted by practical ingenuity, into physical power. . . . From this union of conditions, [we can] forward to a vast multiplication and long succession of [mechanical] contrivances for economizing labor and increasing its produce: and to an ever wider diffusion of the use and benefits of those contrivances.”

The earths surface consists of several jagged slabs of rocks that move at a rate 1-20 centimeters a year. Why do tectonic plates move. how do tectonic plates move?
Answer:
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.

explain whether each of the following comparisons demonstrates the influence of genetics or of envronment on intelligence. -The correlation of intelligence test scores for identical twins raised together is about +.85. For identical twins raised apart, the correlation is about +.72
Answer:
• The first example shows a greater influence of environment on intelligence because the independent variable is the environment (environment in which the twins were raised), not genes.
• The second example shows a greater influence of genetics on intelligence because the independent variable is genes (the types of twins in question), not the environment.
Explanation:
By now we can say that both genetics and environment influence the development of our intelligence. In some cases, it is possible to determine which had more influence.
The correlation of intelligence for identical twins raised together shows the influence of the environment, whereas for twins raised apart shows genetic factors.
What does intelligence mean?Intelligence is a multifactorial phenotypic trait that is influenced by both environmental and genetic factors.
Twins are used for studying the influence of genetic and environmental factors because they have the same genetic background.Intelligence is also a quantitative trait because it is controlled by many different genes.In conclusion, the correlation of intelligence for identical twins raised together shows the influence of the environment, whereas for twins raised apart shows genetic factors.

Josie made $73.29 from a garage sale on Sunday. This is $37.50 less than Saturday’s sales. Complete the equation that could be used to find Saturday’s sales, s.
__ =73.29
Answer:
x - 37.50 = 73.29
Explanation: This would be the equation used to find saturday's sales because the question specified that sunday's sales were $37.50 less than saturday's. So we just need to find out the value we are subtracting the 37.50 dollars from.
It would work out like this:
x - 37.50 = 73.29
x = 73.29 + 37.50 (Bring the value over, change the sign)
x = 110.79
Answer:
s - 37.50 = 73.29
Explanation:
Since Saturday was $37.50 more than Sunday, if you would subtract 37.50 from Saturday you would end up back with Sunday's sales.
