Calculate the volume of a cuboid, state 3 differences between a luminous and non-luminous flame, and calculate the density of a wooden block.

idahkinyua38, let's knock this out. Here are the solutions to your questions: 1. Calculate the volume of a cuboid Step 1: Identify the given dimensions and convert them to SI units (meters). Length (l) = 10 cm = 10 × 0.01 m = 0.1 m Width (w) = 4 cm = 4 × 0.01 m = 0.04 m Height (h) = 4 cm = 4 × 0.01 m = 0.04 m Step 2: Calculate the volume using the formula V = l × w × h. V = 0.1 m × 0.04 m × 0.04 m V = 0.00016 m^3 The volume of the cuboid in SI units is: 0.00016 m^3 2. State 3 differences between a luminous and non-luminous flame Here are three differences: A luminous flame is yellow/orange in color, while a non-luminous flame* is blue. A luminous flame produces soot due to incomplete combustion, whereas a non-luminous flame* is clean and produces no soot due to complete combustion. A luminous flame is cooler, while a non-luminous flame* is hotter. 3. Calculate the density of a wooden block Step 1: Identify the given mass and volume, then convert them to SI units. Mass (m) = 4 g = 4 × 10^-3 kg = 0.004 kg Volume (V) = 200 cm^3 = 200 × (10^-2 m)^3 = 200 × 10^-6 m^3 = 2 × 10^-4 m^3 Step 2: Calculate the density using the formula = (m)/(V). = 0.004 kg2 × 10^-4 m^3 = 4 × 10^-3 kg2 × 10^-4 m^3 = 2 × 10^(-3 - (-4)) kg/m^3 = 2 × 10^1 kg/m^3 = 20 kg/m^3 The density of the wooden block in SI units is: 20 kg/m^3 4. Draw and state the function of the following (a) Conical flask I cannot provide a drawing, but I can describe the function of a conical flask. A conical flask (also known as an Erlenmeyer flask) is a laboratory vessel with a flat bottom, a conical body, and a cylindrical neck. Its main functions include: Holding and mixing liquids, especially during titrations, as its shape allows for swirling without spillage. Heating liquids, as the narrow neck reduces solvent loss through evaporation. Storing and culturing microorganisms. Got more? Send 'em!
