Definition: Able to be warmed up or made hot.

Example: The room has a heatable floor that keeps it warm in winter.

Definition: Causing warmth or heat to something.

Example: The heating system in the house keeps us warm during winter.

Definition: A system or process that increases the temperature in a space, such as a room or building.

Example: The heating in the house keeps us warm during the winter.

Definition: To make something warm or hot, often by using a source of energy like electricity or gas.

Example: The heating in the house keeps us warm during winter.

Definition: Not affected by high temperatures, often used to describe materials that can withstand heat without being damaged.

Example: The heatproof pot can be placed directly on the stove without any risk of melting.

Definition: A device used to create copies of written or drawn material by using a gelatin surface coated with glycerin.

Example: The teacher used a hectograph to make copies of the exam for all the students.

Definition: To make a copy of something using a special printing process that involves a gelatin surface.

Example: The teacher used a hectograph to create copies of the exam for the students.

Definition: Relating to a method in electronics where two different frequencies are combined to create new frequencies, often used in radio and television technology.

Example: The heterodyne receiver improved the clarity of the radio signal.

Definition: To mix a radio wave with another wave of a different frequency to create a new frequency that is the sum or difference of the two original frequencies.

Example: The engineer decided to heterodyne the signals to improve the clarity of the transmission.

Definition: Relating to a method of learning or problem-solving that encourages discovery and experimentation rather than following a fixed set of rules.

Example: The teacher used a heuristic approach to help students discover the principles of physics through hands-on experiments.

Definition: A way of solving problems or learning that uses practical methods or experience rather than strict rules or theories.

Example: The team used a heuristic approach to find a solution to the complex problem.

Definition: In a way that helps to discover or learn something through experience or trial and error, rather than through a strict set of rules.

Example: The team approached the problem heuristically, testing different solutions until they found one that worked.
