How to convert 1348 celsius to kelvin

Celsius and Kelvin are both units for temperature. The relationship between both units is given as;

Kelvin (K) = Celsius ( °C )  + 273

Inserting the values from the question;

Kelvin (K) = 1348 + 273 = 1621 K

Combustibles fosiles ¿Por qué son inflamables los gases naturales?¿Dónde están los gases naturales?¿Cómo podemos sacar el aceite?¿Dónde está el carbón?¿Es el combustible fósil una fuente no renovable? AYUDAA

Answers

Answer:

1) Los gases naturales son inflamables porque el natural contiene metano junto con una pequeña cantidad de otros gases orgánicos, lo que hace que una mezcla de entre 5 y 15% de concentración de gas natural con aire u oxígeno se queme por completo cuando se enciende.

2) El petróleo crudo, que son depósitos de hidrocarburos que se encuentran en depósitos naturales en las formaciones subterráneas de la Tierra, se obtiene perforando un pozo en el yacimiento de petróleo a través del cual se permite que una parte importante del petróleo fluya fuera del yacimiento bajo la presión del yacimiento para recibir procesamiento e instalaciones de almacenamiento en la superficie

3) El carbón se forma cuando se aplica compactación y calor a la turba que proviene de material vegetal muerto enterrado durante un período de varios millones de años.

4) Los combustibles fósiles se consideran una fuente de combustible no renovable porque la velocidad a la que se produce es más rápida que la velocidad a la que se forma.

Una fuente de energía renovable, como la energía eólica, es producida por la naturaleza tan rápido como se consume para generar energía.

How does ocean currents affect climate i need it in 8 sentences.

Answers

Ocean currents move both warm and cool water across many miles. Warm water can be carried to a cooler place like Alaska. It can bring warmer temperatures as well as warmer water to Alaska. Just like the warm water, cold water can do this as well. If cold water moves from Alaska to The Gulf of Mexico, it can cause the water and air to cool. As air travels over the ocean water vapor can condense into it. The current’s flow depends on what variables are in play. There are many different currents that connect together to heat up and cool off as they move.

A microwave oven uses electromagnetic radiation to heat water molecules in food or drink. This radiation has a frequency of 2.45 x 10⁹ Hz. Calculate its energy

Answers

Answer:

1.62 × 10⁻²⁴ J

Explanation:

Step 1: Given and required data

Frequency of this radiation (ν): 2.45 × 10⁹ Hz (2.45 × 10⁹ s⁻¹)Planck's constant (h): 6.63 × 10⁻³⁴ J.s

Step 2: Calculate the energy (E) of this electromagnetic radiation

We will use the Planck-Einstein's relation.

E = h × ν

E = 6.63 × 10⁻³⁴ J.s × 2.45 × 10⁹ s⁻¹ = 1.62 × 10⁻²⁴ J

Which of the following is the mass in grams of 4.25 × 10³ mol of N2?

Answers

Answer:

119,059.5 g/mol

Explanation:

First, find the mass of N2

On the periodic table, nitrogen is 14.007

Because there are two nitrogens, multiply it by 2

14.007*2 = 28.014 g

Now convert... (also don't let that exponent intimidate you! You can change it to 4250 if that makes it easier)

4.25 × 10³ mol * 28.014 g/1 mol = 119059.5 g/mol
