Thermal Properties and Temperature 1 - Y10C

Why must cookware made from glass be specially designed?

• Ordinary glass would shatter due to uneven expansion when rapidly heated.

• Glass cookware is lighter than metal cookware.

• Glass is a better conductor of heat than metal.

• Glass cookware is more affordable than other materials.

What is the relationship between pressure and temperature in gases?

• As temperature increases, the pressure of a gas increases if the volume is constant.

• As temperature increases, the pressure of a gas decreases if the volume is constant.

• Pressure and temperature are unrelated in gases.

• Increasing pressure always leads to a decrease in temperature.

What is the effect of thermal expansion on overhead power lines?

• Overhead power lines are left slightly loose to accommodate contraction in cold weather.

• Overhead power lines become taut and may snap in hot weather.

• Overhead power lines are insulated to prevent thermal expansion.

• Overhead power lines are replaced every season to manage thermal effects.

What is the difference between temperature and heat?

• Temperature is the total energy of all particles in an object, while heat refers to how hot or cold something is.

• Temperature is a measure of the average kinetic energy of particles, while heat is the energy transferred between objects.

• Temperature and heat are the same; both refer to how hot or cold something is.

• Temperature refers to how hot or cold something is, while heat (or thermal energy) refers to the total energy of all particles in an object.

What is the role of expansion gaps in engineering?

• Expansion gaps allow for the movement of structures to accommodate thermal expansion.

• Expansion gaps are used to increase the weight of structures.

• Expansion gaps are designed to enhance the aesthetic appeal of buildings.

• Expansion gaps prevent bending or breaking of structures like bridges and railways due to thermal expansion.

How does the kinetic theory of matter explain temperature?

• Temperature is a measure of the total mass of particles in a substance.

• Temperature is a measure of the average kinetic energy of particles in constant motion.

• Temperature is determined by the color of the substance.

• Temperature is the measure of the distance between particles.

Pressure is inversely proportional to the Volume, likewise volume does not exist here.

What happens to particles in a substance as temperature rises?

• The particles gain kinetic energy and move faster.

• The particles lose kinetic energy and move slower.

• The particles remain stationary and do not change.

• The particles become denser and sink.

What happens to gases when they are heated?

• Gases contract and become denser.

• Gases expand the most because their particles move freely and collide with container walls with more force.

• Gases remain unchanged in volume.

• Gases turn into liquids.

What are bimetallic strips used for?

• They are used in thermostats to activate or deactivate a switch based on temperature changes.

• They are used in electrical circuits to increase voltage.

• They are used in construction to reinforce structures.

• They are used in cooking to measure food temperature.
