为探究物质的某种特性，某小组的同学先做如下实验：他们在甲、乙两只完全相同的烧杯中分别放入100g和200g的温水，实验时，让它们自然冷却，并利用温度计和计时器测量水的温度随时间的变化情况，记录数据分别如表一、表二所示(设甲、乙两杯水每分钟放出的热量相等)

    表一：m₁=100g

时间(min)	0	2	4	6	8	10	12	14	16
温度(℃)	36	35	34	33	32	31	30	30	30
降低温度(℃)	0	1	2	3	4	5	6	6	6

表二：m₂=200g

时间(min)	0	4	8	12	16	20	24	28	32	36
温度(℃)	36	35	34	33	32	31	30	29	28	28
降低温度(℃)	0	1	2	3	4	5	6	7	8	8

(1)分析比较表一和表二中数据可知，实验时，两杯水所处环境的温度是________的．(填“相同”或“不同”)

(2)分析比较表一(或表二)中第一行和第三行数据及相关条件，可得出的初步结论是：

      ________________________________________，放出的热量与降低的温度成正比．

(3)分析比较表一和表二中第三列、第四列、第五列等数据及相关条件，可得出初步结论是：________________________________________________________________．

    (4)进一步综合分析比较表一和表二中的数据及相关条件，还可得出的初步结论是：

      ___________________________________________________________________．
