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

The mass of sample = 10 g
<h3>Further explanation </h3>
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:
ρ = density , g/ml
m = mass , g
v = volume , ml
Density is 5 g/ml and sample is 2 ml,so :
ρ = 5 g/ml
V = 2 ml
The mass :
