The amount of water that 1 kg of sand can absorb depends on the type and size of the sand particles. Generally, 1 kg of sand can absorb around 0.3-0.5 liters of water. However, this can vary based on factors such as the porosity and density of the sand. It's important to note that different types of sand may have different absorption capacities. **

Vacation can be both stress and relaxation, depending on the individual and the circumstances. For some people, planning and organizing a vacation can be stressful, especially if there are a lot of logistics to consider. However, once on vacation, the change of scenery and break from routine can be very relaxing and rejuvenating. It ultimately depends on the person's mindset and how they choose to approach their vacation. **

Mixing potting soil with sand in a 1:1 ratio for lavender is not recommended. Lavender prefers well-draining soil, and while sand can improve drainage, a 1:1 ratio may lead to soil that is too sandy and does not hold enough moisture. It is better to mix potting soil with sand in a 1:2 or 1:3 ratio to ensure proper drainage while still retaining enough moisture for the lavender to thrive. Additionally, adding organic matter such as compost or peat moss can also help improve the soil structure for lavender. **

The specific heat capacity of sand is approximately 0.84 J/g°C. To calculate the energy needed to heat 1 kg of sand by 1 degree Celsius, we can use the formula: Energy = mass x specific heat capacity x temperature change. Plugging in the values, we get: Energy = 1000g x 0.84 J/g°C x 1°C = 840 J. Therefore, it would take 840 joules of energy to heat 1 kg of sand by 1 degree Celsius. **

There are approximately 55.5 moles of water in 1 liter or 1 kilogram of water. Since one mole of water contains 6.022 x 10^23 molecules, there are about 3.34 x 10^25 water molecules in 1 liter or 1 kilogram of water. **

1 * 1 is another way of writing 1 * 1 * 1 because when you multiply a number by 1, the value of the number remains unchanged. In other words, multiplying by 1 does not alter the original number. Therefore, when you multiply 1 by 1, the result is still 1, and when you multiply that result by 1 again, it remains 1. This is why 1 * 1 is equivalent to 1 * 1 * 1. **

1 bar water pressure is equivalent to the pressure exerted by a column of water that is 10 meters (33 feet) in height. **

To pave on a 1 meter high sand, you would first need to compact the sand to create a stable base for the paving. This can be done using a plate compactor or by wetting and tamping down the sand. Once the sand is compacted, you can then lay a layer of gravel or crushed stone to further stabilize the base. Finally, you can lay the paving stones or bricks on top of the prepared base, making sure they are level and properly spaced. It's important to ensure proper compaction and base preparation to prevent settling and shifting of the paving over time. **
