Explanation

When an object is placed very close to a concave mirror, its image will be:

• Virtual (not a real image that can be projected onto a screen)
• Upright (not inverted)
• Larger in size than the object (magnified)

Explanation

• Thermal energy is the form of energy that is transferred from one body to another due to a difference in temperature, and is received from heat.
• It is the energy of motion of particles in a substance, such as atoms or molecules, and is often referred to as "heat energy".

Explanation

• When the child rubs the balloons with wool, the balloons become statically charged with the same type of charge (either positive or negative).
• When two objects with the same charge are brought near each other, they repel each other.

Explanation

• Mammals are a group of animals that have babies that are born alive (viviparous), are warm-blooded (endothermic), have mothers that feed their babies with milk (lactation), and have fur, hair, or skin and a spine (vertebrates).
• Examples: humans, dogs, cats, bears, whales, dolphins, lions, monkeys, elephants and sharks etc.

Explanation

• Permanent magnets are materials that retain their magnetism for a long time.
• They are typically difficult to magnetize, but once magnetized, they retain their magnetic properties.

Explanation

• Laboratory thermometers typically have a range of 10°C to 110°C.
• It allowing for precise temperature measurements in a variety of laboratory settings.

Explanation

• Carbohydrates are the body's primary source of instant energy.
• They are broken down into glucose.
• Which is absorbed into the bloodstream and transported to cells throughout the body.
• Where it is converted into energy.

Explanation

• Traits are the characteristics or attributes of an organism that are determined by its genetic makeup.
• Such as eye color, hair color, skin color, blood group and shape of nose and lips.

Explanation

• Air expands the most for a given rise in temperature, due to its low density and high thermal expansion coefficient.
• This is why hot air rises and cool air sinks, driving convection currents in the atmosphere.

Explanation

• Methyl orange is a pH indicator that changes color in response to changes in acidity or basicity.
• In an acidic medium, it is orange (or red), and in a basic medium, it turns yellow.
