Is chemical change better than physical change?
"Better" is not the term you would use for comparing physical to chemical without defining the principle of what is better, but a chemical change is a more permanent change that will more than likely require input of energy.
How Does Thermal Energy Cause Change?
Thermal energy can cause changes in materials by either heating or cooling them. Heating can expand materials, change their physical state (e.g. melting), or initiate chemical reactions. Cooling can contract materials, change their physical state (e.g. freezing), or slow down reactions. Thermal energy essentially provides the energy needed for these changes to occur.
Is liquid evaporating a chemical or physical change?
physical change, its molecules are gaining energy and evaporating
Is state is physical or chemical?
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.
How can energy cause change?
Energy can cause change by transferring or transforming into different forms, such as thermal, mechanical, electrical or chemical energy. This change can result in movement, growth, temperature change, or other processes in the system that the energy is acting upon. Ultimately, energy is the driving force behind all processes and reactions in the universe.
Is a heating process onto carbon dioxide a chemical reaction or a physical reaction?
Heating carbon dioxide is a physical reaction because it does not change the chemical makeup of the substance, only its physical state. The heat energy causes the carbon dioxide molecules to vibrate more rapidly, increasing their kinetic energy and leading to a phase change from solid to gas.
Which describes a physical change that results from the addition of thermal energy?
The physical change resulting from the addition of thermal energy can include melting of a solid into a liquid, such as ice turning into water. This process involves breaking the intermolecular forces between particles, allowing them to move more freely and change their arrangement without changing their chemical composition.
Which uses more energy a plasma or an LCD monitor?
An LCD will have a generally lower energy requirement than a Plasma monitor. But Plasma monitors energy requirements change with the brightness. If something on the screen is dark, it will use less energy.
Why do teens who do sports need more calories?
A calorie is a unit of energy. When anyone does physical exercise, the body uses more energy than when the person is not moving. In order to get that extra energy, the person must eat more. In addition, teens generally need to eat more calories because their bodies use energy to grow, build bones, and fully develop.
Who needs more energy secretary or 11-year-old child?
An 11-year-old child generally requires more energy in terms of physical activity and growth than an Energy Secretary, who primarily engages in mental and administrative tasks. Children are in a developmental stage that demands significant energy for play, learning, and overall growth. Conversely, an Energy Secretary's energy needs are more related to cognitive functioning and decision-making rather than physical exertion. Therefore, the child typically needs more energy overall.
What has more energy Gatorade or monster energy?
Monster Energy typically contains more caffeine and a higher total energy content compared to Gatorade. While Gatorade is designed primarily for hydration and replenishing electrolytes during physical activity, Monster Energy is formulated to provide a quick energy boost through caffeine and sugar. Therefore, in terms of energy-boosting effects, Monster Energy generally has more energy than Gatorade.
What Is a physical change in matter?
A physical change is a change that affects one or more properties of matter. For example, if you have a popsicle and it melts, it's looks change but the physical properties don't
