Question 5
A)
A chemist is performing a chemical reaction under a fume hood. The chemist has a set of beakers, flasks, and tubes set up under the fume hood, with various liquids being combined inside the glass containers. The fume hood is turned on in order to withdraw any toxic gases and expel them outside the building.

**Question 1:**
A) Which option is an example of an open system?
**Response:**
**an erupting volcano**
(An erupting volcano is an example of an open system as it exchanges both matter and energy with its surroundings.)
---
**Question 2:**
A) Which statement accurately describes a reaction with very high heat energy?
**Response:**
**many molecular collisions occurring quickly**
(At high temperatures, the kinetic energy of molecules increases, leading to more frequent and energetic collisions.)
---
**Question 3:**
A) A reaction is occurring in a test tube. How is heat transmitted to the surroundings?
**Response:**
**Molecules collide with the glass, and the glass molecules then transmit that energy to the outside.**
(Heat is conducted through the glass of the test tube and then transferred to the surrounding environment.)
---
**Question 4:**
A) Which statement is true for an open system?
**Response:**
**Heat and matter can both transfer between the system and the surroundings.**
