What is the enthalpy change to burn 37.5 g of ammonia?
The enthalpy change to burn 37.5 g of ammonia (NH3) can be calculated using the standard enthalpy of formation of ammonia and the balanced chemical equation for its combustion. The enthalpy change will depend on the specific conditions of the reaction, such as temperature and pressure.
Can alcohol percent change because of different temperatures?
Yes, the alcohol percentage of a liquid can change with temperature because temperature affects the volume of the liquid. As temperature increases, the volume expands, leading to a decrease in alcohol concentration in the liquid. Conversely, as temperature decreases, the volume contracts, causing an increase in alcohol concentration.
How does a substances temperature change when the average kinetic energy of its particles increases When it decreases?
When the average kinetic energy of a substance's particles increases, the substance's temperature also increases because temperature is a measure of the average kinetic energy of the particles. Conversely, when the average kinetic energy of a substance's particles decreases, the substance's temperature decreases because there is less molecular movement and lower energy levels overall.
How does the temperature change during an exothermic reaction?
During an exothermic reaction, the temperature increases because heat is released as a byproduct of the reaction.
How do intermolecular forces change as temperature increases?
As temperature increases, intermolecular forces weaken. This is because higher temperatures provide more energy to molecules, causing them to move faster and overcome the attractive forces between them.
How does relative humidity change with temperature?
As temperature increases, relative humidity decreases. This is because warmer air can hold more moisture, so the relative humidity percentage decreases as the air temperature rises.
How does the ac resistance of a diode change as the voltage increases?
When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
Does the temperature change if the average kinetic energy of a substance changes?
When Ave KE increases temperature increases.
How does the solubility of gas change with decreasing temperature?
It increases
When temperature increases solids change to a?
gas or a liquid
How does temperature change with depth below earths surface?
temperature increases with depth
How do we show the change in temperature when it gets warmer?
The numerical value of the temperature increases.
What is the relationship between resistance and temperature?
• ntc 'negative temperature coefficient': its resistance decreases as the temperature increases• ptc 'positive temperature coefficient': its resistance increases as the temperature increases
What will happen when ammonia gas is cooled and compressed?
When ammonia gas is cooled and compressed, it undergoes a phase change and transforms into a liquid state. As the temperature decreases and pressure increases, the kinetic energy of the ammonia molecules reduces, allowing intermolecular forces to draw them closer together. This process is commonly used in refrigeration systems, where ammonia serves as a refrigerant. Eventually, if the conditions are right, ammonia can solidify into a solid form known as ammonium hydrate.
How does the movement of particles of matter change when temperature decreases?
Increases
How does a substances temperature change when the average kinetic energy of it's particles increases?
As the average kinetic energy of a substance increases, the temperature will increase.
