Nothing. Josh will never know.
Salt water has a lower freezing point and a higher boiling point.
The effect depends on the salt enthalpy of dissolution.
Salt lowers the melting or freezing point of water. The effect is termed 'freezing point depression'. Therefore frozen salt water melts faster and remain melted for long.
when salt is added to ice, salt being an impurity, reduces the inter molecular space between ice molecules. As we know that ice, in order to melt, contracts, i.e reduces the inter molecular space between its molecules. salt increases this activity and so ice melts at a lower temperature than it usually does. i.e salt decreases the melting point of ice.
Salt doesnt slow down the melting of ice. It actually speeds up the melting in most cases because the addition of salt lowers the temperature required for the water to freeze. That's why they will often put salt on the roads after a snow storm...to melt the ice.
Yes, and this depends on the chemical and physical nature of the salt and also on the concentration.
Salt water has a lower freezing point and a higher boiling point.
yes
Baking soda is classified as a salt. As such, it has a similar effect as table salt when placed on ice, helping it melt by lowering the freezing point. of the water.
Adding salt to ice lowers its temperature and melting point. This is because salt disrupts the normal freezing process of water, causing the ice to melt at a lower temperature than it would without salt.
Dissolving a salt (NaCl, CaCl2) in water the heat of dissolution is released and the melting point of ice is then decreased.
Rock salt lowers the freezing point of water, causing the ice to melt. This melting process requires energy, which is absorbed from the surroundings, resulting in a cooling effect.
The effect depends on the salt enthalpy of dissolution.
Salt lowers the melting point of ice.
The melting point of salt (Sodium Chloride) is 801 °C
Salt will melt it the fastest but too much salt can damage concrete and blacktop. Sand or cat litter work well to help with traction but have little effect on melting.
You think to dissolution, not to melting. The solubility is increased by: - rise of the temperature (for the sodium chloride the effect is not so important) - stirring - using very fine powdered salt
