the temperature decreases
Rocks refers to ice cubes. A drink served on the rocks means that it is poured over ice cubes, and served with the ice cubes in the drink.
because Germans usually drink their water at room temperature
The cold water molicules (or ice molicules) abosorb the heat of the drink and begin to move faster. however the drink is not warm enough for the drink to melt the ice cubes completely. the over all effect is that all of the molicules in the drink slow down thus becoming colder.
They melt because the heat in the air is warmer than the temperature of the ice cubes.
Hollow ice cubes are faster to make and have more surface area in your drink.
If Ice cubes are melting in water, the temperature of both the ice cubes and the water will be exactly the freezing temperature of water: 32F, 0C. You cannot change this. You can add heat to make the ice cubes melt faster, but the extra heat will have no effect on the temperature, It will all go to melting the ice cubes.
place ice cubes in water or air at a warmer temperature than 32 Deg.F. place ice cubes in water or air at a warmer temperature than 32 Deg.F.
Ice cubes explode in a drink because they are melting at a fast rate. The ice cannot contract fast enough to keep up with the melting, which causes it to crack.
The ice will melt to water and dilute whatever liquid it is in, so yes, your drink of whiskey will become weaker as this happens.
A cold glass of water sometimes causes water vapour from the surrounding air to condense onto the surface of the glass. The same thing happens with ice cubes, but instead the water droplets condensing on the surface, they will instantly freeze and 'weld' ice cubes together. They also can stick together if put into a drink, where again, the water in the drink near the surface of the ice cube may get cold enough to freeze and cause the ice cubes to fuse together.
No. Unless adding ice cubes to soda means you drink less soda.
the temperature of ice cubes are lower than the temperature of the water around them. The heat energy from the water is used up in the process of melting the ice, so the water temperature drops.
