Is a physical change what happens when chemical bonds break and new bonds form?
No, a physical change does not involve breaking or forming chemical bonds. It only involves changes in physical properties like size, shape, or state of matter. Chemical changes involve the breaking and forming of chemical bonds to create new substances.
When a substance undergoes a phase change it still has a definite A mass B shape C volume D temperature?
C. volume. During a phase change, the substance's volume remains constant even though there may be a change in its mass, shape, or temperature.
Where does a physical change takes place?
When a physical change takes place, a certain element or chemical will change its shape and in many cases, the volume too. Water takes the shape of the mold casing once it freezes.
What 4 factors can change the protein shape?
pH, temperature, presence of inhibiting proteins
Does an ice lolly have a fixed shape?
An ice lolly starts in a solid state but can change shape as it melts due to heat from outside sources or ambient temperature.
Can solid change it shape?
Yes, It can change... To be a liquid or a gas :)OR by applying forces..... Yes it can change its shape by the alteration of temperature.
What makes the lens in your eye change shape?
Increased water pressure can change the shape of your eye. If this happens, it is always an indicator to get your eyes checked professionally.
What is the term used for a change in a protein's three dimensional shape or confirmation due to disruption oh hydrogen bonds disulfide bridges or ionic bonds?
The term for a change in a protein's three-dimensional shape due to disruption of hydrogen bonds, disulfide bridges, or ionic bonds is called denaturation. This process can be caused by factors such as heat, pH changes, or chemicals, leading to loss of protein function.
At what temperature does rennin work best?
The Kinetic Theory states that with increased temperature, molecules receive more energy, resulting in them speeding up their movement. If the milk and the rennin molecules are moving faster, they will collide more often. The collisions will also have more energy so more of them are successful. Therefore the rate of reaction increases. However, above 37°C rennins optimum temperature, the rate of reaction will decrease. This is because the rising temperature affects the hydrogen and ionic bonds which determine the shape of the enzyme. As these bonds are broken the shape of the active site changes and the molecules.
What determines the shape of proteins?
The sequence of amino acids. The chemical bonds between amino acids, and temperature and ph. and its environment
What is Shape memory effect?
the change of shape of a metal at low temperature by loading and regaining of original shape by heating it,is known as shape memory effect
Do the properties of glass changed by heating?
Yes, heating glass can change its properties. When heated, glass may become softer, more malleable, and easier to shape due to increased molecular mobility. However, overheating can cause the glass to lose its shape, crack, or even melt, depending on the temperature achieved.
How does a large change in temperature or pH affects proteins?
They come apart and lose there shapeA large change in temperature or ph will cause protiens to come apart and lose their shape.
Is a physical change what happens when chemical bonds break and new bonds form?
No, a physical change does not involve breaking or forming chemical bonds. It only involves changes in physical properties like size, shape, or state of matter. Chemical changes involve the breaking and forming of chemical bonds to create new substances.
Does mercury change size and shape?
Mercury does not change size and shape easily because it remains in liquid form at room temperature, unlike solid substances which can change shape more readily under pressure or temperature changes. Mercury's unique properties make it a useful liquid metal for various applications.
What is the shape of the graph at the melting and freezing points of water what does this shape tell you about the temperature?
Well, honey, the graph at the melting and freezing points of water is flat as a pancake. This shape tells you that the temperature remains constant during these phase changes. So, don't expect any temperature changes while water is busy melting or freezing, darling.
When a substance undergoes a phase change it still has a definite A mass B shape C volume D temperature?
C. volume. During a phase change, the substance's volume remains constant even though there may be a change in its mass, shape, or temperature.
