What is the definition for thermal energy for kids?
thermal energy is energy in the form of heat.
Why does a aluminum sinks?
Aluminum (aluminium) has a higher density than water.
Does freezing gain thermal energy?
Yes. When ice is converted to water, thermal energy is required. When the water is converted back to ice, the same amount of thermal energy is released.
Does water absorb thermal energy during condensation?
No, water releases thermal energy during condensation. It absorbs thermal energy during evaporation, which is why the evaporation of sweat cools your skin.
The most famous examples of thermal energy?
A 12 ounce glass of water at 70 degrees has more thermal energy than a 12 ounce glass of water at 60 degrees.Adding ice to a glass of water causes the temperature of the water to decrease because the thermal energy in the water causes the ice to melt.A grill gives off thermal energy by burning propane.The sun's thermal energy heats our atmosphere.Thermal energy from a hot stove is transferred to a metal pot and causes the water molecules to move faster increasing the temperature of the water.
Does the temperature of water change more slowly than the temperature of land?
Yes, water has a higher thermal capacity.
Why is the temperature of soil higher than the water when heated by the sun?
Because water has a higher thermal capacity than soil and also water tends to circulate which soil can't do.
What is the definition for thermal energy for kids?
thermal energy is energy in the form of heat.
Why does water stay cooler than land?
The thermal capacity is higher for water than land, therefore the land is able to cool faster than the water. The water takes a longer time to heat up and cool off than the land.
Why does a aluminum sinks?
Aluminum (aluminium) has a higher density than water.
Why water is a very efficient thermal buffer?
Water has a high heat capacity, which can be described as "thermal inertia". That means that water can absorb a large amount of heat energy.
Does water or steel have a higher heat capacity?
1000 g of water
Why water is used as coolant as well as heater in hot water bags?
Because it has a high thermal capacity.
Why hydro gels have higher capacity to hold water?
because they have higher viscosity
What properties applies to aluminum and not iron?
Aluminium is paramagnetic, iron is ferromagnetic Aluminium has a low density, iron is more dense Aluminium is not corroded in water, iron is easily corroded The hardness of aluminium is lower The price of aluminium is greater The melting point of iron is significantly greater The thermal and electrical conductivity of aluminium are more important Iron has a greater chemical reactivity ................................................................... etc.
What is temperature in physics?
Temperature is a measure of the concentration of thermal energy. Consider a lit match and a beaker of room temperature water. The water will have more thermal energy (due to water's high specific heat capacity) than the flame, but the thermal energy of the flame is more concentrated.
How does heat capacity makes water a good heat sink?
If a body of water has a high heat capacity, it can store more thermal energy making it a good heat sink.
