Answer:Calor y temperatura son dos conceptos diferentes pero estrechamente relacionados. Observa que tienen diferentes unidades: la temperatura típicamente tiene unidades de grados Celsius (^\circ\text C  

∘

Cdegrees, start text, C, end text) o Kelvin (\text KKstart text, K, end text), y el calor tiene unidades de energía, joules (\text JJstart text, J, end text). La temperatura es una medida de la energía cinética promedio de los átomos o moléculas en el sistema. Las moléculas de agua en una taza de café caliente tienen una mayor energía cinética promedio que las moléculas de agua en una taza de té helado, lo que también significa que están moviéndose a una velocidad más alta. La temperatura también es una propiedad intensiva. Esto significa que no depende de qué tanta cantidad tengas de una sustancia (¡siempre y cuando esté toda a la misma temperatura!). Por esta razón, los químicos pueden utilizar el punto de fusión para poder identificar una sustancia pura: la temperatura a la cual se derrite es una propiedad de la sustancia que no depende de la masa de una muestra.

A nivel atómico, las moléculas en cada objeto están constantemente en movimiento y chocando entre sí. Cada vez que chocan, pueden transferir energía cinética. Cuando dos sistemas están en contacto, se va a transferir calor del sistema más caliente al más frío por medio de choques moleculares. La energía térmica va a fluir en esa dirección hasta que los dos objetos están a la misma temperatura. Cuando esto ocurre, decimos que están en equilibrio térmico.

Explanation:

Al calor a veces se le llama una magnitud de proceso, porque está definido en el contexto de un proceso por el cual se puede transferir energía. No decimos que una taza de café contiene calor, pero podemos hablar del calor transferido de la taza de café caliente a tu mano. El calor también es una propiedad extensiva, así que el cambio de temperatura que resulta al transferir calor a un sistema depende de cuántas moléculas hay en el sistema.

lisov135 [29]

Answer:

The heat of the reaction is 105.308 kJ/mol.

Explanation:

Let the heat released during reaction be q.

Heat gained by water: Q

Mass of water ,m= 1kg = 1000 g

Heat capacity of water ,c= 4.184 J/g°C

Change in temperature = ΔT = 26.061°C - 25.000°C=1.061 °C

Q=mcΔT

Heat gained by bomb calorimeter =Q'

Heat capacity of bomb calorimeter ,C= 4.643 J/g°C

Change in temperature = ΔT'= ΔT= 26.061°C - 25.000°C=1.061 °C

Q'=CΔT'=CΔT

Total heat released during reaction is equal to total heat gained by water and bomb calorimeter.

q= -(Q+Q')

q = -mcΔT - CΔT=-ΔT(mc+C)

q=-1.061^oC(1000 g\times 4.184J/g^oC+4.643 J/^oC )=-4,444.15J=-4.444 kJ

Moles of propane =\frac{1.860 g}{44 g/mol}=0.0422 mol

0.0422 moles of propane on reaction with oxygen releases 4.444 kJ of heat.

The heat of the reaction will be:

\frac{4.444 kJ}{0.0422 mol}=105.308 kJ/mol

What unit is not a measured volume
kodGreya [7K]
The base units of length and volume are linked in the metric system. By definition, a liter<span> is equal to the volume of a cube exactly 10 </span>cm<span> tall, 10 </span>cm<span> long, and 10 </span>cm<span> wide. Because the volume of this cube is 1000 cubic </span>centimeters<span> and a </span>liter<span> contains 1000 milliliters, 1 milliliter is equivalent to 1 cubic centimeter.</span>

Which word names melted rock and minerals found beneath Earth's crust?
Anna11 [10]

before the lava rises to the earth's surface it's called magma. Although lava and magma are often used interchangeably, technically magma is the name for the hot molten rock (mixed with gases and mineral crystals) that collects in chambers beneath the Earth's crust.
