Answer:
The water will continue to heat up as the experiment progresses.
Explanation:
When a person's fingers are cold or has a muscles ache, one can use chemical hand warmers to heat them up. There are two types of chemical hand warmer products, and they all depend on exothermic chemical reactions to work.
However, ammonium chloride dissolution is endothermic but its crystalization is exothermic. When used as a hand warner with a calorimeter, it is found that the temperature of the water increases steadily due to the crystalization of the ammonium chloride. Hence the answer.
Non electrolytes are Pentacarbon decahydride, Phosphorus pentachloride, Glucose.
<u>Explanation:</u>
Non electrolytes do not exist as ions in aqueous solution. Since it does not get dissociated into ions, these non electrolytes do not conduct electricity when it is dissolved or it is heated or melted.
Pentacarbon decahydride is a non electrolyte.
Magnesium chloride is an electrolyte.
Copper phosphate is an electrolyte
Sulfur trioxide is an electrolyte.
Aluminum oxide is an electrolyte
Phosphorus pentachloride do not get dissociated into its ions so it is a non-electrolyte.
Glucose gets dissolved in water but do not dissociate into ions, so it is a non electrolyte.

¡Hola!
En este caso, dada la información para estos problemas, procedemos de la siguiente manera, basado en las leyes de los gases ideales:
1. Una masa de aire ocupa un volumen de 5 litros a una temperatura de 120 °C Cual será el nuevo volumen si la temperatura se reduce a la mitad:
Aqui, utilizamos la ley de Charles, asegurándonos que la temperatura está en Kelvin:
2. Un gas ideal ocupa un volumen de 4000 ml a una presión absoluta de 1500 kilo pascal Cual será la presión si el gas es comprimido lentamente hasta 750 kilo pascal a temperatura constante?
Aquí, utilizamos la ley de Boyle, dado que la temperatura se mantiene constante, calculando el volumen, ya que lo que se da es la presión final:
3. Un gas ocupa un volumen de 200 litros a 95°C y 782 mmHg Cual será el volumen ocupado por dicho gas a 65°C y 815 mmHg:
Aquí, utilizamos la ley combinada de los gases ideales, asegurándonos que las temperaturas están en Kelvin:
¡Saludos!
