What is the process by which plants convert sunlight into energy called?
Photosynthesis
What is the flow of electric charge called?
Electric Current
What is a chemical reaction?
A process in which substances are transformed into different substances with different properties.
What is the formula to calculate speed?
Speed = Distance / Time
What is the outermost layer of the Earth called?
Crust
What are the two main products of photosynthesis?
Oxygen and glucose
What is the unit of measurement for electric current?
Ampere (A)
What are the reactants and products in a chemical equation?
Reactants are the starting substances, while products are the substances formed after the reaction.
What is the SI unit of force?
Newton (N)
What is the process by which rocks are broken down into smaller pieces by weathering and erosion?
Mechanical weathering
Which pigment in plant cells absorbs light energy for photosynthesis?
Chlorophyll
What is the formula for calculating electrical power?
Power (P) = Voltage (V) × Current (I)
What is the law of conservation of mass?
The law states that mass is neither created nor destroyed in a chemical reaction; it is conserved.
What is the difference between speed and velocity?
Speed is a scalar quantity that only specifies the magnitude of motion, while velocity is a vector quantity that specifies both the magnitude and direction of motion.
What is the term for the continuous movement of water on, above, and below the Earth's surface?
Water Cycle
In which part of a plant cell does photosynthesis primarily occur?
Chloroplasts
What is the term for a material that does not allow electric current to pass through it easily?
Insulator
What is the difference between exothermic and endothermic reactions?
Exothermic reactions release heat energy to the surroundings, while endothermic reactions absorb heat energy from the surroundings.
What is Newton's first law of motion, also known as the law of inertia?
An object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity, unless acted upon by an external force.
What is the theory that explains the movement of Earth's lithospheric plates?
Plate Tectonics
What gas is taken in by plants during photosynthesis?
Carbon Dioxide
What is Ohm's Law and what is the formula associated with it?
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance. The formula is V = I × R, where V represents voltage, I represents current, and R represents resistance.
What is the difference between a physical change and a chemical change?
A physical change alters the physical properties of a substance without changing its chemical composition, while a chemical change results in the formation of new substances with different properties.
What is the relationship between force, mass, and acceleration, as described by Newton's second law of motion?
The force acting on an object is equal to the mass of the object multiplied by its acceleration. F = m × a.
What is the process by which a solid directly changes into a gas without passing through the liquid state?
Sublimation
