Explain why substances with hig specific heats take longer to heat up than substances wit the same mass which have low specific heats?
Type your answer here... A substance with high specific heat means it can absorb alot more heat energy before its temperature increases. A substance with low specific heat cannot absorb alot of heat energy so its temperature increases quickly because it cant absorb the heat. Remember there is a difference between Heat energy and Temperature. The ocean can absorb alot of heat energy but still feel like its cold in temperature. The tip of a needle can be at 1000 degrees temperature but there is hardly any actual heat energy in it because its so small.
Substances are changed into different substances when bonds break and form during?
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
What is the measure of kinetic energy of a substances molecules?
temperature is the measure of the average kinetic energy of a substances molecules, though energy is in joules and temperature is in Kelvin.
What are the 5 characteristics of chemical change?
During a chemical change the structure of molecules (as chemical composition) is changed. Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds
When matter undergoes change of state what does it absorb or release?
Energy.
Can a change in matter neither release nor absorb energy?
Yes.
When matter changes can it absorb heat energy or release heat energy without a corresponding change in temperature?
no.
Which substances will show the smallest change in temperature when equal amounts of energy are absorbed?
Substances with high specific heat capacities, such as water, will show the smallest change in temperature when equal amounts of energy are absorbed. This is because these substances can absorb a lot of heat energy without a significant increase in temperature.
Does the Bunsen burner absorb energy as heat?
The Bunsen burner release energy as heat of combustion.
When most substances absorb heat energy they?
expand
Does vaporization absorb or release energy?
Vaporization absorb energy.
What are two effects caused by chemical change?
the substance will become an entirley new substance.
The substance that would absorb the most heat energy with the least temperature change would be one kilogram of?
Water has a high specific heat capacity, meaning it can absorb a large amount of heat energy while experiencing only a small temperature change. Therefore, one kilogram of water would absorb the most heat energy with the least temperature change compared to other substances.
What is the specific heat capacity of ethanol and how does it affect its ability to absorb and release heat compared to other substances?
The specific heat capacity of ethanol is 2.44 J/gC. This means that ethanol can absorb and release heat more efficiently compared to other substances, as it requires less energy to change its temperature. This property makes ethanol a good candidate for use in applications where heat transfer is important.
What is the heat capacity of ethanol and how does it affect its ability to store and release thermal energy?
The heat capacity of ethanol is 2.44 J/gC. This means that ethanol can absorb and release a moderate amount of thermal energy compared to other substances. Its heat capacity affects its ability to store and release thermal energy by determining how much heat it can hold and how quickly it can change temperature.
What does you eat?
Any edible substances that can be digested by the digestive enzymes,can be early absorb in the bloodstream and also assimilated through the process of oxidization to release energy.
