How much energy is required to change 80g of ice at -30 degrees celsius to steam at 140 degrees Celsius?
To calculate the total energy required, we need to consider the energy required for each phase change using the specific heat capacities and latent heat of fusion/vaporization. The energy required can be broken down into: heating the ice from -30°C to 0°C, melting the ice at 0°C, heating the resulting water from 0°C to 100°C, boiling the water at 100°C, and heating the steam from 100°C to 140°C. The total energy can be calculated using these components.
How much heat energy in megajoules is needed to convert 7 kilograms of ice at -9c to water at 0c?
To convert 7 kilograms of ice at -9°C to water at 0°C, you need to calculate the energy required for each phase change. First, calculate the energy to raise the ice temperature from -9°C to 0°C using the specific heat capacity of ice. Then, calculate the energy required to melt the ice into water using the latent heat of fusion of ice. The total energy will be the sum of these two values.
Which phase has the most energy?
The phase with the most energy is the gas phase. Gas molecules have higher kinetic energy compared to solid or liquid molecules because they have more freedom to move and collide with each other at higher speeds.
If you add enough thermal energy a material may change its?
First, it'll change it's temperature, and with this comes change in size, usually expansion. Then it can change its physical properties, it can become softer, or harder. Next you may change its phase: If you're starting out with a solid, it may melt to liquid phase; a liquid may go to gas phase; a gas may go to plasma phase. Or, if oxygen is available, eventually it may start to burn. Or, depending on the material, which could well be a mixture of different molecules, these might interact with each other, or they might fragment into smaller molecules.
Where does the energy go since heat of vaporization does not result in a temperature change?
The energy required for vaporization is used to overcome intermolecular forces holding the liquid together, rather than increasing the temperature. This energy is used to break the bonds between molecules and change the state from liquid to gas.
Why does it take 80 calories to convert 1 gram of water to 1 gram of steam?
Water molecules attract each other; energy is required to overcome that attraction. In other words, the change of phase implies a change in potential energy.
Draw and discuss the relationship of heat of fusion and heat of vaporization?
The heat of fusion is the energy required to change a substance from solid to liquid at its melting point, while the heat of vaporization is the energy required to change a substance from liquid to gas at its boiling point. Both values are specific to each substance and represent the amount of energy needed to break intermolecular forces during phase changes, with vaporization requiring more energy than fusion due to the additional change in state.

What is the energy required to go from liquid to gas called?
The latent heat of vaporization
What are the processes in changing one phase to another phase of matter?
Changes in state are called phase transitions. Each of the phase transitions has a technical name and many have common names. The change from solid to liquid is fusion (or melting). The change from liquid to solid is solidification (or freezing). The change from liquid to gas is vaporization (or boiling). The change from gas to liquid is condensation. The change from solid to gas is sublimation.
Can you skip any players in Phase 10?
No, in Phase 10, players cannot skip their turn. Each player must take their turn and complete the required phase before moving on to the next phase.
Which phase change is endothermic?
The 3 types of endothermic phase changes are the movement from solid to liquid, the movement from liquid to gas, and the movement form gas to plasma. Endothermic is the absorbing of heat.
What are the main energy storing products of each phase of photosynthesis?
The main energy-storing product of the light-dependent phase of photosynthesis is ATP (adenosine triphosphate) and NADPH. In the light-independent phase, the main energy-storing product is glucose.

What is the transformation of a physical state of a substance into a different physical state?
The transformation of a physical state of a substance into a different physical state is called a phase change. An example of this is water changing from solid (ice), to a liquid (water), to a gas (steam).
