Answer:
OB. Energy transfer would occur between the copper bars and the surroundings.
Explanation:
We define an isolated system as a system in which there is neither exchange of material nor energy while an open system is one in which materials and energy can be exchanged with the environment.
Given an open system consisting of two copper bars at different temperatures, energy will not only be exchanged between the copper bars but also between the copper bars and the environment.
Answer:
191 packages of pepperoni
Explanation:
Each pizza would have 13 slices and 15 pieces of pepperoni on each one.
(because same amount of pepperoni and olives)
13 × 15 so each pizza has 195 pieces of pepperoni
138 (number of pizzas) × 195 (pieces of pepperoni)
26910 (pieces of pepperoni) / 141 (amount in each package)
= 190.85
so 191 packages
Answer:
Increasing Surface Area
Explanation:
A greater surface area (meaning more, smaller particles) allows for more opportunity for particles to collide. On the other hand, decreasing temperature and removing a catalyst would only decrease the number of collisions, and the clumping option doesn't make much sense. Hope this helps!
