Answer:
The "graduated cylinder" is measuring a "volume of water" in "milliliters".
Option: D
Explanation:
Measuring of "liquid" in "milliliters" we use "graduated cylinder". This represents the "volume of the water" or the "liquid". The "graduated cylinder" is labelled with the dimensions in the "milliliters". Measuring with "graduated cylinder" is some what difficult because of the "meniscus", this "meniscus" is the "curvature" of the surface of the water in the "graduated cylinder". The only problem is "meniscus" is attached to the edges of the cylinder but not in the middle of the cylinder. While looking at the cylinder the "meniscus" is not straight, hence the person should keep the "graduated cylinder" at his eye level.
Answer:
a. The second run will be faster.
d. The second run has twice the surface area.
Explanation:
The rate of a reaction is proportional to the surface area of a catalyst. Given the volume (V) of a sphere, we can find its surface area (A) using the following expression.
The area of the 10.0 cm³-sphere is:
The area of each 1.25 cm³-sphere is:
The total area of the 8 1.25cm³-spheres is 8 × 5.61 cm² = 44.9 cm²
The ratio of 8 1.25cm³-sphere to 10.0 cm³-sphere is 44.9 cm²/22.4 cm² = 2.00
Since the surface area is doubled, the second run will be faster.
Answer:
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. ... The fire's heat causes molecules in the pan to vibrate faster, making it hotter. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster.
