What statement about the energy of a phase change is true?
Melting is an endothermic change, because ice absorbs energy from its surroundings as it melts.
How does an endothermic process differ from an exothermic process?
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
How does the energy of a substance change during an exothermic change?
During an exothermic change, energy is released from the substance in the form of heat to the surroundings. This results in a decrease in the internal energy of the substance, leading to a decrease in its temperature.
What is a reaction that absorbs energy?
The type of reaction that absorbs energy is endothermic. This process takes the energy from its surroundings, absorbs it, and creates heat.
Definition of endothermic?
Endothermic reactions or processes absorb heat from their surroundings to proceed, causing a decrease in temperature of the surroundings. Energy is required for the reaction to occur, resulting in a decrease of the system's internal energy.
The system adsorbs energy from its surroundings?
The system absorbs energy from its surroundings, increasing its internal energy. This can lead to temperature increases or other forms of energy storage within the system. Adsorption is the process of collecting and retaining molecules on the surface of a material.
What type of phase change does a substance absorb energy from its surroundings?
When a substance absorbs energy from its surroundings, it undergoes a phase change known as endothermic. This results in an increase in the substance's internal energy, allowing it to transition from one state to another (e.g., from solid to liquid or from liquid to gas) by absorbing heat from its surroundings.
What statement about the energy of a phase change is true?
Melting is an endothermic change, because ice absorbs energy from its surroundings as it melts.
A system absorbs 640J heat and does work of 260J the change in internal energy of the system will be?
the system has been given internal energy of 640j and the work system does on surroundings is 260j. therefore by first law of thermodynamics the internal energy of system increases by (640-260=380)j.
What is the relationship between the work done by an expanding gas and the change in its internal energy?
The work done by an expanding gas is directly related to the change in its internal energy. When a gas expands, it does work on its surroundings, which can lead to a change in its internal energy. This change in internal energy is a result of the work done by the gas during the expansion process.
A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10 2 kJ of work on the system What is the change in internal energy of the system?
3.0 x10 1 kj A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10³ kJ of work on the system. What is the change in internal energy of the system? --- 224 kj
How does an endothermic process differ from an exothermic process?
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
Where does energy come from an endothermic reaction?
Energy in an endothermic reaction comes from the surroundings, as the reaction absorbs heat or energy from its surroundings to proceed. This absorption of energy allows the reactants to overcome the activation energy barrier, enabling the reaction to occur.
How can you determine whether an equation is endothermic or exothermic?
To determine if an equation is endothermic or exothermic, you can look at the overall energy change. If the reaction absorbs energy from the surroundings, it is endothermic. If the reaction releases energy into the surroundings, it is exothermic. This can be determined by comparing the energy of the reactants to the energy of the products.
How does an endothermic reaction change the entropy of the surroundings?
An endothermic reaction which absorbs heat from the surroundings decreases the entropy of the surroundings. This is because the surroundings lose thermal energy during the reaction, leading to a decrease in the disorder or randomness of the surroundings.
How does the energy of a substance change during an exothermic change?
During an exothermic change, energy is released from the substance in the form of heat to the surroundings. This results in a decrease in the internal energy of the substance, leading to a decrease in its temperature.
What is a reaction that absorbs energy?
The type of reaction that absorbs energy is endothermic. This process takes the energy from its surroundings, absorbs it, and creates heat.
