Is heating a cup of tea a chemical change?
Heating a cup of tea is a physical change, not a chemical change. The heat causes the molecules in the tea to move faster, but the chemical composition of the tea remains the same.
What happens to the heat stored in the metal when the metal is poured into the Styrofoam cup of water?
When the metal is poured into the Styrofoam cup of water, the heat stored in the metal is transferred to the water and the cup. This transfer of heat causes the temperature of the water and the cup to increase, as the metal cools down.
Is pouring soda into a cup chemical change?
No, pouring soda into a cup is a physical change because the molecules of the soda remain the same. Chemical changes result in the formation of new substances with different chemical properties.
How can I create a DIY calorimeter for measuring heat energy in chemical reactions?
To create a DIY calorimeter for measuring heat energy in chemical reactions, you can use a simple setup with a Styrofoam cup, a thermometer, and a stirrer. Fill the cup with a known volume of water and measure its initial temperature. Then, add the reactants to the water and stir while monitoring the temperature change. By calculating the change in temperature and knowing the specific heat capacity of water, you can determine the heat energy released or absorbed during the reaction.
Is drinking milk a chemical change?
Distilling water is a physical change. When water is distilled, any trace impurities will left in the container it was distilled from. These impurities were not chemically bonded to the water, instead, they formed a mixture with the water, and a mixture is always created physically.
Is heating a cup of tea a chemical change?
Heating a cup of tea is a physical change, not a chemical change. The heat causes the molecules in the tea to move faster, but the chemical composition of the tea remains the same.
Is water condensing in a cup physical or chemical change?
physical change

Is stirring an egg in with a cup of water a chemical change?
no, it's a physical change
Is making a cup coffee a chemical change?
No it is a physical change.
Is pouring soda into a cup chemical change?
No, pouring soda into a cup is a physical change because the molecules of the soda remain the same. Chemical changes result in the formation of new substances with different chemical properties.
Stirring sugar into a cup of tea is chemical?
Stirring sugar into a cup of tea is a chemical change because when you evaporate the tea you can not get the sugar back, instead you get a mixture of glucose and fructose. It is also a chemical change.
Is baking cup cakes a chemical change?
Yes, it's a chemical change. When you mix the ingredients, you can't take out the ingredients again.
Is using hot water to expand a metal cup a physical or chemical change?
Using hot water to expand a metal cup is a physical change. The change in size and shape of the cup is due to the expansion of the metal atoms when heated, but the chemical composition of the metal cup remains the same.
Is evaporation of water from a cup of water a physical or chemical change?
physical
Since a hot cup of coffee loses heat more rapidly than a lukewarm cup of coffee would it is correct to say that a hot cup of coffee will cool to room temperature before a lukewarm cup of coffee will?
A hot cup of coffee will cool down at a certain rate, but as the coffee cools, the rate at which it cools slows down. This is why a "lukewarm" cup of coffee cools down so slowly. Even though the warm cup of coffee is cooling down quicker at first, the lukewarm cup essentially has a "head start" on the way to room temperature.
Is mixing a 0.5 cup of of vinegar with a gallon of milk a chemical change?
Yes
