Evaporation is the process by which a liquid changes into a gas or vapor, typically occurring at the surface of the liquid at temperatures below its boiling point.

Okay, let's tackle question 5. a) i) Evaporation is the process by which a liquid changes into a gas or vapor, typically occurring at the surface of the liquid at temperatures below its boiling point. ii) Condensation is the process by which a gas or vapor changes into a liquid, usually due to cooling. iii) Sublimation is the process by which a solid changes directly into a gas or vapor without first melting into a liquid, and vice versa. b) Step 1: Identify the given values. Voltage, V = 12 V Resistance, R = 3 Step 2: Apply Ohm's Law to calculate the current. Ohm's Law states that V = IR, where I is the current. Rearranging for current: I = (V)/(R) Step 3: Substitute the values and calculate. I = 12 V3 I = 4 A c) i) Here are three differences between a porcupine and a hedgehog: 1. Size:* Porcupines are generally much larger than hedgehogs. 2. Quills:* Porcupine quills are typically longer, sharper, and can detach easily, while hedgehog spines are shorter, less sharp, and generally remain attached. 3. Defense mechanism:* Porcupines may release their quills as a defense, whereas hedgehogs primarily roll into a tight ball to protect themselves with their spines. ii) The difference between a Vertebrate and an Invertebrate is the presence or absence of a backbone (vertebral column). Vertebrates are animals that possess a backbone, while invertebrates are animals that do not have a backbone. d) i) According to the Brønsted-Lowry definition, an Acid is a proton (H^+) donor. ii) According to the Brønsted-Lowry definition, a Base is a proton (H^+) acceptor.
