1.3 kg water = 1300 grams.
q(Joules-heat energy) = mass * specific heat * change in temperature
q = (1300 g)(4.180 J/gC)(100 C - 20 C)
= 4.3 X 105 Joules of heat energy
========================
Energy can be transferred through conduction, where heat is transferred via direct contact between objects. Energy can also be transferred through convection, where heat is carried by a fluid like air or water. Lastly, energy can be transferred through radiation, where electromagnetic waves carry energy from one location to another.
the study is called PHYSICS.
When hot water and cold water are mixed, the kinetic energy of the hot water particles is transferred to the cold water particles through collisions. This transfer of energy causes the overall temperature of the mixture to become more uniform as the particles mix and reach thermal equilibrium.
Energy is transferred in the water cycle primarily through the processes of evaporation and condensation. When water evaporates from surfaces like oceans and lakes, it absorbs heat energy from the surroundings, which cools those areas. As water vapor rises and cools in the atmosphere, it releases that stored energy during condensation, forming clouds and ultimately precipitation. This transfer of energy drives weather patterns and influences climate systems.
Approximately 38% of the energy in glucose is transferred to ATP during cellular respiration. The rest of the energy is released as heat.
Energy.
When thermal energy is transferred to water, the water molecules absorb the energy and their kinetic energy increases. This causes the temperature of the water to rise, eventually leading to the water boiling and turning into steam.
Energy can be transferred through water mainly through conduction and convection. In conduction, heat energy is transferred from one water molecule to another through direct contact. In convection, water currents are created by temperature differences, moving energy throughout the water body.
In the heating of water, thermal energy is transferred to the water from an external heat source. This causes the water molecules to gain energy and vibrate more rapidly, leading to an increase in temperature.
When your head is on water, the energy being transferred is heat. Heat is transferred from your head to the water, causing your head to cool down. When your head is on a pillow, the energy being transferred is mechanical energy. The weight of your head exerts pressure on the pillow, which causes the pillow to compress and convert that pressure into stored mechanical energy.
Energy is transferred by a water wave as it moves through the water. This energy causes the particles of water to oscillate in a circular motion as the wave passes, transmitting kinetic energy from one particle to the next.
Energy and momentum are transferred by water waves. As the water molecules move in a wave motion, they transfer energy from one point to another. This energy transfer creates the movement we observe in water waves.
When water is heated on a stove, thermal energy is transferred to the water. This causes the water molecules to move faster and increase in temperature.
kinetic
Ocean waves get their energy from the wind, which creates friction on the surface of the water. This energy is transferred through the water by the movement of water particles in a circular motion, causing the waves to propagate and travel across the ocean.
The melting point of water is 0 degrees Celsius. When ice at 0 degrees Celsius is exposed to a temperature higher than 0 degrees Celsius, it will melt at a rate determined by the amount of heat energy being transferred to the ice.
The energy from the boiling water is transferred to the mug through conduction. The hot water molecules collide with the mug's molecules, causing them to vibrate and increase in temperature.
