Is exploding dynamite a chemical or physical change?

Is exploding dynamite a chemical or physical change?

Among these options, an explosion of dynamite is caused by a chemical change. Because the explosion process is a chemical reaction and it is an exothermic reaction. The dynamite is made up of nitroglycerin, sorbents and stabilizers and dynamite is an explosive material. When the dynamite explodes, a chemical changes.

Which of the following are examples of physical change?

Examples of Physical Changes

• Crushing a can.
• Melting an ice cube.
• Boiling water.
• Mixing sand and water.
• Breaking a glass.
• Dissolving sugar and water.
• Shredding paper.
• Chopping wood.

Is forming dews on grasses a physical or chemical change?

Condensation is the process a material undergoes as it changes from a gas to a liquid. Dew is the result of water changing from a vapor to a liquid. Hence,the formation of dew is a physical change.

Why is dynamite exploding a chemical change?

dynamite is an example of a rapid chemical reaction. proceed more slowly, but all chemical reactions release or absorb energy. This energy can take many forms, such as heat, light, sound, or electricity. called exergonic (ek sur GAH nihk) reactions.

What type of change is formation of dew?

Condensation is the process a material undergoes as it changes from a gas to a liquid. Dew is the result of water changing from a vapor to a liquid. Dew forms as temperatures drop and objects cool down.

Is exploding dynamite a chemical change chemical property physical change or physical property?

The explosion of fireworks is an example of chemical change. During a chemical change, substances are changed into different substances. Another words, the composition of the substance changes.

Is a bomb exploding endothermic or exothermic?

off in a reaction is primarily in the form of heat, the reaction is called an exothermic reaction. and the explosion of dynamite are exothermic reactions.

What happens to the nitroglycerin in a stick of dynamite?

Over time, regardless of the sorbent used, sticks of dynamite will “weep” or “sweat” nitroglycerin, which can then pool in the bottom of the box or storage area.

What happens when you turn over a box of dynamite?

Over time, regardless of the sorbent used, sticks of dynamite will “weep” or “sweat” nitroglycerin, which can then pool in the bottom of the box or storage area. For that reason, explosive manuals recommend the repeated turning over of boxes of dynamite in storage.

What’s the shelf life of a stick of dynamite?

The maximum shelf life of nitroglycerin-based dynamite is recommended as one year from the date of manufacture under good storage conditions. Over time, regardless of the sorbent used, sticks of dynamite will “weep” or “sweat” nitroglycerin, which can then pool in the bottom of the box or storage area.
