If the volume is constant, the density does not change with temperature. With increasing temperature there is still the same number of molecules confined to the same volume of space, so no difference in density.
No, the specific gravity of sea water can vary depending on factors like temperature, salinity, and pressure. However, at standard conditions, the average specific gravity of sea water is around 1.025.
The query is incomplete. So it has to be: What will be the rise in temperature in both? Let us use the formula Q = m s t. As m remains constant and Q too remains constant then st, the product must be a constant. Hence s and t are inversely related. Higher the value of s then less the rise in temperature. For gold its value will be t = Q/m * 1/s = 5/0.03 = 500/3 degree rise ie 167 degree nearly For iron the value will be t = 5/0.11 = 500/11 = 45.5 degree nearly
Because density is an intensive property, it does not depend on the amount of material. Density is a ratio between mass and volume, D=M/V. That specific ratio is constant for any material. For example, the smallest sample of aluminum and the largest sample of aluminum have a density of 2.70 g/cm^3 at room temperature. Density does change with temperature because temperature affects volume. The density of all samples of aluminum at its melting point is 2.375 g/cm^3.https://en.wikipedia.org/wiki/Aluminium
temperature. This is known as the kinetic theory of gases, which states that the average kinetic energy of gas molecules is directly proportional to the temperature of the gas, regardless of the type of gas.
The definition of density is mass per unit volume. For any object or sample of a substance, it can be calculated as (mass) divided by (volume). If two objects or samples with the same volume have different masses, the one with the greater mass has greater density. If two objects or samples with the same mass have different volumes, the one with the greater volume has smaller density.
It could be many things such as temperature or pressure.
Density reason is that the density of a uniform material is constant Density is independent of the size and shape of the sample.
At room temperature, all samples of liquid H2O must have the same boiling point, which is 100 degrees Celsius or 212 degrees Fahrenheit at standard atmospheric pressure.
Avogadro stated that two samples of ideal gases at the same temperature, pressure, and volume contain the same number of molecules.
It seems like your question was cut off. If you meant to ask whether all samples of a substance can be identical, the answer is no. While samples of a pure substance will have the same chemical composition, variations can occur due to impurities or different physical states. Factors such as temperature, pressure, and the method of preparation can also lead to differences in properties between samples.
Stirring the liquid bath ensures a uniform temperature throughout the bath, which is important for accurate and consistent measurements. It helps to minimize temperature variations within the bath, ensuring that the samples are exposed to a constant and homogeneous temperature environment during the determinations.
A constant temperature room is a controlled environment where the temperature is maintained at a specific, stable level, regardless of external conditions. This type of room is often used in scientific research, quality control, and storage of sensitive materials to ensure consistent results and prevent temperature-related variations. The precise temperature is typically regulated using heating, ventilation, and air conditioning (HVAC) systems, enabling accurate experiments and preserving the integrity of samples or products.
Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.

A water bath is used in chemical experiments to provide a stable and uniform temperature environment for samples. This helps to control the temperature of reactions or facilitate heat-sensitive experiments. The water bath also helps to reduce evaporation and maintain a constant temperature throughout the experiment.
False. The density of a substance can vary depending on factors such as temperature and pressure. Additionally, impurities in a sample can also affect its density.
The tissue samples are not alive. They are not living or moving like a living human. The effects of the drugs may be different on 'non living' samples may be different to the effects on a non-living human.
