Answer 1

Answer:

4. Similarities between Clinical Thermometer and a laboratory thermometerBoth are made of glass and consist of a long narrow glass tube.At one end, both of them have a bulb.Bulbs of both the thermometers consist of mercury.Celsius scale is present in both the thermometer.

5. Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.

Examples of Radiation

Examples of RadiationExamples include: A burning candle emits radiation in the form of heat and light. The Sun emits radiation in the form of light, heat, and particles. Uranium-238 decaying into Thorium-234 emits radiation in the form of alpha particles.
