Answer:
60 grams of ice will require 30.26 calories to raise the temperature 1°C.
Explanation:
The amount of heat (Q) to raise the temperature of 60.0 g of ice by 1°C can be calculated from:
<em>Q = m.c.ΔT,</em>
where, Q is the amount of heat released or absorbed by the system.
m is the mass of the ice (m = 60.0 g).
c is the specific heat capacity of ice (c = 2.108 J/g.°C).
ΔT is the temperature difference (ΔT = 1.0 °C).
∴ Q = m.c.ΔT = (60.0 g)(2.108 J/g.°C)(1.0 °C) = 126.48 J.
<em>It is known that 1.0 cal = 4.18 J.</em>
<em>∴ Q = (126.48 J)(1.0 cal / 4.18 J) = 30.26 cal.</em>
It is important because if the sample size is smaller, outliers could skew the data more than if it was large.
Explanation:
When a soil lacks earthworm, it will be poorly aerated and organic matter will be lacking.
Earthworms burrow through the soil and leaves holes and pores around in the soil.
- Soil air is an important component that makes up the soil.
- Earthworm are good burrowers that penetrates the soil and creates pores.
- This facilitate infiltration of water into the soil and also the circulation of air.
- Also, since they are decomposers, they the leave the soil rich and filled with organic matter.

When a weak acid is titrated against a strong base, the pH of the solution rises, levels off through the buffer zone, and then rises quickly to reach the equivalence point.
<h3>What is titration?</h3>
Titration is a typical research center technique for quantitative investigation synthetic to decide the convergence of a recognized analyte. Titration is a crucial cycle in the creation of cheddar. For this situation, titration is significant while estimating the pH and acridity of the underlying milk being utilized to make the cheddar. Corrosive base titration is a quantitative investigation of convergence of an obscure corrosive or base arrangement. Titration, otherwise called titrimetry, is a typical lab strategy for quantitative substance investigation that is utilized to decide the convergence of a distinguished analyte. A reagent, called the titrant or titrator is ready as a standard arrangement. A known fixation and volume of titrant responds with an answer of analyte or titrand to decide focus. The volume of titrant responded is called titration volume.
