Answer:
Explanation:
First you should calculate the volume of a big sphere,so:
Then you calculate the volume of a small spehre, so:
Finally you subtract the two quantities:
Answer:
Thermal insulation. Thermal insulation is the reduction of heat transfer (i.e. the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence.
Explanation:
An organic compound is one which consists of a chain of carbon atoms with other atoms bonded to the chain.
Pentane has 5 carbon atoms with surrounding hydrogens.
glucose is a chain of 6 carbon atoms
butane is similar to pentane
water has no carbon atoms, and the central atom is oxygen ---> therefore it is inorganic!
1.50 atm(760 mmHg/1 atm)=1140 mmHg
Precise is the close proximity of repeated measurements. In order to be precise, you need two or more measurements.
Accurate is the close proximity to the real (or expected) measurement.
<u>For Example: </u>
You are at the grocery store buying watermelons. The sign says that the watermelons all weigh 2 lbs. You weigh 3 of them on the scale next to the watermelon display. Their weights are 1.77, 1.80, and 1.82.
→ The <u>scale is precise</u> because it weighs all 3 of them at nearly the same value.
→ The <u>scale is not accurate </u> because their weights are not close to the expected value of 2.0
You take one of the watermelons to the cashier. The scale at the checkout counter weighs it as 1.99. The scale at the checkout counter is accurate. You cannot determine the precision of the scale at the checkout counter because you have no other values to compare it to.
Answer: Precise CANNOT be determined by one measurement.
Accurate CAN be determined by one measurement.
