answer A.a new substance is formed
Answer:
Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.
In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

What is the relationship and the PROPORTIONS between Joules, lime, Cal, and Kcal?
Joules is the SI unit of Energy (heat energy).
Calorie, also called lime, is the amount of heat required to raise the temperature of 1 gram of pure water by 1°C or 1 K.
1 calorie = 4.186 J
A thousand calorie is equal to 1 kcal.
Hence,
1 kcal = 1000 calories = 4186 J
In Portugese/Em português
Joules é a unidade SI de energia (energia térmica).
Caloria, também chamada de cal, é a quantidade de calor necessária para elevar a temperatura de 1 grama de água pura em 1°C ou 1 K.
1 caloria = 4,186 J
Mil calorias é igual a 1 kcal.
Portanto,
1 kcal = 1000 calorias = 4186 J
