Are water droplets condensing on a soda can on a hot summer day exothermic or endothermic?
exothermic
What would be a chemical change melting ice cream in the sun crushing a soda can mixing salt and sugar or burning wood in the fireplace?
Burning wood
Susie dropped some ice cubes into her soda after dinner After a few minutes she noticed that the ice had melted into the soda What statement correctly explains what Susie witnessed?
Heat from the soda transferred into the ice cube, which melted the ice.
Crushed soda can physical or chemical change?
physical change
What reaction will cause the contain to feel colder?
Endothermic reactions can cause the container to feel colder. A simple example would be just mixing baking soda and vinegar.
Is baking soda and vinegar a endothermic change?
no
Is baking soda and vinegar an endothermic or exothermic reaction?
This is a chemical change because once the substances are put together to form a gas it cannot be changed.
Does ice cubes in soda make it more healthy?
No. Unless adding ice cubes to soda means you drink less soda.
Why does a glass of ice cubes in water melt faster than a glass of ice cubes in a glass of soda?
Ice cubes that are in water are in full contact with a liquid medium with high rate of heat transfer. in soda, some of the surface of the ice is in contact with gas bubbles that have low rate of heat transfer. Liquid transfers heat (melting the ice) faster than air.
What melts faster water ice cubes or soda ice cubes?
Water :)

Does ice melt faster in regular or in diet soda?
Ice should melt faster in diet soda than in regular soda because the sugar in regular soda makes the liquid more dense. The increased density will delay the transfer of heat that causes melting from the surrounding liquid to the ice cube.
Do ice cubes melt faster in water or soda?
depends!
Is baking soda and citric acid a endothermic or exothermic reaction?
It is endothermic. The heat of the water in the calorimeter decreases (giving you a -deltaH), which means that the system absorbed heat, making the reaction endothermic.
Why does water ice cubes melt faster than soda ice cubes?
because water heats up faster
